Triangle TIC is an isosceles triangle with a vertex angle I. If the measure of Angle I = 90degrees, then find the measure of angle T.
15degrees, 45degrees, 90degrees, 30degrees

Solution:

Given that TIC is an isosceles triangle with vertex angle I

Angle I = 90

From the property of an isosceles triangle, when the vertex angle is 90, the other two angles apart from the vertex angle are equal.

Hence, angle T = angle C

We know that the sum of interior angles of a triangle is 180

Angle T + angle I + angle C = 180

X + 90 + X = 180

2x + 90 = 180

2x = 180 - 90 = 90

x = 45

Therefore, angle T = 45 degrees

Triangle TIC is an isosceles triangle with a vertex angle I. If the measure of Angle I = 90degrees, then find the measure of angle T.

Summary:

Triangle TIC is an isosceles triangle with a vertex angle I. If the measure of Angle I = 90degrees, then the measure of angle T is 45 degrees.
