Given data:
The given figure of the triangle.
The measure of the side a is,
a=4 units.
The measure of the side b is,
b= 4 units.
The measure of the angle C is 90 degrees.
As the side a is equal to side b, it means the given triangle is isosceles right angle triangle.
The measure of the angle B is equal to the measure of the angle A which is 45 degrees.
The side c can be calculated as,
Thus, a= 4 units, b=4 units, c=4√2, ∠C=90 degrees, ∠A= 45 degrees, and ∠B=45 degrees.
