Question

1 (a) What will be the other angles of a right angled isosceles triangle?

Answer 1

Answer:

The other angles of an isosceles right angled triangle are 45 degree.

Step-by-step explanation:

The first angle of the triangle is 90 degree as it is right-angled

As the triangle is isosceles, the other angles are 45 degree as its two opposite sides are equal.

Answer 2

Given,

A right-angled isosceles triangle.

To find,

The value of the other two angles.

Solution,

The value of the other two angles will be 45° and 45°.

We can easily solve this problem by following the given steps.

According to the question,

We have a right-angled isosceles triangle.

We know that in an isosceles triangle the two sides are equal and their corresponding angles are also equal.

Now, it is given that one of the angles is 90°.

Let's take the second angle to be x°.

Second angle = third angle = x°

We know that the sum of three angles in a triangle is 180°.

90+x+x = 180°

2x+90 = 180°

2x = (180-90)°

2x = 90°

x = 90/2°

x = 45°

Hence, the other two angles are 45° each.
