Triangle Chapter question. Similarities.​

Answer 1

Answer:

Step-by-step explanation:

Since ax/bc = ay/yc. (Given)

so, XY || BC

Let, angle AXY =1

angel AYX=2

angle ABC=3

angle ACB=4

Now, 1 = 2 ........ (1). (Given)

Also, 1 = 3. .........(2). (Corresponding angle)

& 2 = 4 ..........(3). (Corresponding angle)

From eq. (1) (2) &(3),

2 = 4

So,. AB=AC. ( Sides opp. To equal angles are equal)

Therefore, triangle ABC is isoceles triangle
