Question

△TIC is an Isosceles triangle with a vertex angle I. If ∠I = 90°, then find the measure of ∠T. (1 point)
A.15°
B.45°
C.90°
D.30°

Answer 1

Base angles of an isoseceles triangle are equal.

Answer 2

So it's 90? @Easyaspi314

Answer 3

No. You have a triangle with one angle at 90 degrees. Thats what it says in your problem. You want to find the measure of angle T. Angle T is one of the 2 left over angles in the triangle, and the 2 leeft over angles are equal (becuase it is an isosceles triangle).

Answer 4

Hint: All 3 angles of a triangle must add up to 180 degrees.

Answer 5

It's 45?
