Cho tam giác AbC ( AB=AC) . Các tia phân giác của góc B, C cắt AB và AC tại E, F. Chứng minh BE=CF. Gọi I là giao điểm của BE và CF . Chứng minh AI là phân giác của góc A

idk lol xd

step-by-step explanation:

ez do it yourself lazy

solution:

we have to construct

∠m nt ≅ ∠p qr

the steps to draw this construction are

step 1: use a compass to draw an arc from point q which intersects the side pq at point a and the side qr at point b.

step 2: draw a segment nt and use the same width of the compass to draw an arc from point n which intersects the segment nt at a point x.

step 3:

step 4: join points n and y using a straightedge.

step 3:

option (d).maintaining the same width of the compass as ab, draw an arc from point x such that it intersects the arc drawn from n in a point y.

to draw   congruent angles , 1. width of compasses while drawing two angles should be same i.e from point at which angle has to be drawn, 2.the distance between the two points where the compass intersects the two sides should be same while drawing any two congruent angles.

if you need just tell me and i will come to the rescue.

step-by-step explanation:

x=-7

step-by-step explanation:

x+3=-10

-10+3=-7

x=-7
