△ABC中,AB=AC,延长CA到P,再延长AB到Q,使得AP=BQ,求证△ABC的外心O与A,P,Q,四点共圆.不太懂
分析一、O是外心,作△ABC的外接圆⊙O,并作OE⊥AB于E,OF⊥AC于F,连接OP、OQ.易知OE=OF,BE=AF,从而Rt△OPF≌Rt△OQE,于是∠P=∠Q,从而O、A、P、Q四点共圆.
分析二、延长BA至G,使AG=AP,连接OP、OA、OG、OQ,并作OE⊥AB于E(图略).利用△PAO≌△PGO和△QEO≌△GEO也可证得结论.

On the annual training budget of some confusion in the formulation


Annual training as operational plans, annual training plan must answer what the company training program, how to do it, how many resources, what would be the income and other basic issues. One of the budget work is a key aspect of how to do this work for the effective conduct annual training of great significance. Annual training budget plan's basic tasks include training costs to determine the total cost of the project budget. Practice to the training budget report output as a result. Practice,sac hermes birkin, the year spent similar, budget management innovation can not talk about, whether it is technically still on the process, even if there is also a bit on the improved management tools. But for the determination of the total cost, high-level decision-making to promote the high-end resources for other work, but can not be a substantial breakthrough. An annual training budget and the reasons for the development of confusion 1, budget decision-making cycle length submit a budget up, high-level decision-makers how to think about it? What are the criteria to judge? Horizontal reference, or vertical reference? Is top down or bottom up? Training managers how to provide quantitative, accurate,franklin marshall pas cher, reasonable training budget total, and even the direction of the management mechanism using the formulation, budget management process improvement project? Whether the training manager must provide their own rigorous argument, detailed data, and clear training objectives and benefit analysis? In practice, we often find that the training budget discussions, the discussion went, the annual plan portfolio design of the second hot spot, is the second difficulty. Many companies in the specific methods of work, there is less scientific approach, leading to low budget quality and efficiency, and ultimately control the effect is not obvious. 2, the training is difficult to determine the total annual budget practice, most enterprises in the annual training budget, there is a proposition difficult to solve: how much to invest this year in the end money? Experience in the practice of law school now represent the mainstream, such as the proportion method, reference method, adjustment method, due to the budget breakdown and the lack of scientific basis, often to the empirical data of other companies, make another racking our brains to see the data, feel bad, or does not support high-level, and then slightly adjusted, so the total budget report up, with predictable results. 3, the project budget unit is difficult to quantify first portfolio always lead to high-level design challenge,ralph lauren pas cher, then the decomposition of the project budget is quantified. Many of our project-specific decomposition is always difficult, for many reasons, including the project approach to training, mainly determines the total number of trainees training resource requirements. But this is the most difficult in the beginning of two will be able to completely confirm. 4, non-deterministic cost of the project needs training and development is not actually stay in the training of management, as well as training and development needs. Such as the type of individual investment strategy, training, systems improvement or process change, project-specific investment, and so on. How to estimate this cost? Second, develop the annual training budget of several key 1, to provide high-level decision-making basis rigorous training managers in many of our difficulties are often encountered in the budget approval complain about high-level training, do not know, not very professional, random racking our brains, are unwilling to invest, etc., but is unable to calmly reflect on their own inadequacies. In solving problems is a We can design the portfolio recognized on the basis of scientific analysis to quantify the performance, careful communication and promote the decision-making. Not simply to emphasize the effectiveness of training on problem solving, through the influential head to fight the use of force training committee to shake the owner of such ideas, but should be made periodic training programs and the benefits of training, lack of negative statements of budget adversely affected. 2, the budget strategy and process of science science speaking,abercrombie france, the total annual training budget is calculated based on the total project budget from, and finally the total training budget during a high-level support decomposition balance, clear support for control work. This is the Saying the Practice, training of management executives is how to do it? Generally is a In other words, calculate the total budget, then the training needs of the various systems for distribution. Many enterprises within the system's training needs are often just the cost requirements, such as how much money a particular manufacturing sector, to do several training and so on. At this point, training in management If the lack of arguments, argument unreasonable, or high-level recognition is not enough, it may cycle several times,
