In a right angle triangle, one angle is of 90 degrees. Then the measure of the angle 3 will be ∠3 = 90° – ∠2.
What is the triangle?
A triangle is a three-sided polygon with three angles. The angles of the triangle add up to 180 degrees.
We know that in a right angle triangle, one angle is of 90 degrees.
And the angle sum of the triangle is 180 degrees. Then we have
90° + ∠2 + ∠3 = 180°
∠3 = 90° – ∠2
