In the following figure, the circles are light bulbs connected to some other light bulbs. Initially, all light bulbs are off. When you touch a light bulb, this light bulb and all its neighbours are lit. At least how many light bulbs do you have to touch to light all the light bulbs?
In the following figure, AB=AC, AD=AE, and BE,CD intersect at O. Prove that OA bisects ∠DAE. 答案 Since AB=AC,AD=AE,∠BAE=∠CAD, we have △ABE≌△ACD. Therefore, ∠E=∠D.Since ∠COE=∠BOD,CE=AE−AC=AD−AB=BD, we have △COE≌△BOD. Therefore CO=BO.Since we also...
