Question

16. If triangle ABC is isosceles, and if AB = BC and

Answer 1

39, C

Explanation:

If angle A = 39, then the angle C is equal to A. This may seem like a weird question, but it’s the way that the triangle is positioned.

Also, you can prove this by looking at the equation provided in the prompt.

B is the vertex that they are creating this problem from, therefore, it may be helpful to turn the triangle around!

Answer 2

C. 39

Explanation:

If AB = BC, and angle A is 39 degrees. we can assume that angle C would have a similar angle.

Since in △ABC , AB=BC

∴ the triangle is isoceles.

In an isoceles triangle the angles opposite to equal sides are equal.

∴∠A=∠C

This means that C.39 is the correct answer
