If Triangle alphabet is one isosceles best angle, basic angle would certainly be same to 45 degree. that is because, in an isosceles best triangle, 2 angle remains equal (45) and one is larger.(90)In short, her ptcouncil.net would be 45Hope his helps!

You are watching: Triangle abc is an isosceles right triangle. what is the measure of a base angle? °


The measure of base angle is 45°

Step-by-step explanation:

Given that triangle alphabet is an isosceles ideal triangle.

we have actually to discover the measure up of basic angles.

As provided triangle is appropriate angled triangle therefore one angle which is no a base angle is the 90°

Also the triangle abc is isosceles because of this two sides of triangle space equal and angles opposite to the equal sides room equal.

Let these equal angles which are base angle is x°

By angle sum property of triangle,

the sum of all angle of triangle equates to to 180°






Hence, the measure of base angle is 45°

Hi there! :)


According come the exterior angle theorem, the edge ∠ADC is equal to the amount of ∠C and ∠B. Therefore:

120 = (15 + 5) + (22x + 4)

Combine choose terms:

120 = 37x + 9

Subtract 9 from both sides:

111 = 37x

Divide both sides by 37:

x = 3.
