Question

9.
In a right-angled triangle, what is the sum of the measure of two angles?
a. 180°
b. 90⁰
​

Answer 1

Answer:

b. 90°

Step-by-step explanation:

Because in a right angled triangle, one side measures 90°

And the sum of all sides of a triangle is 90°

Therefore, the sum of the remaining sides will be 90°.

Answer 2

Answer:

The answer is b) 90 degree.

Step-by-step explanation:

The right triangle has one 90 degree angle and two acute (< 90 degree) angles.  Since the sum of the angles of a triangle is always 180 degrees...

y + z = 90 degrees

The two sides of the triangle that are by the right angle are called the legs...  and the side opposite of the right angle is called the hypotenuse.
