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.
