Question

4. In a right-angled isosceles triangle, one angle
is 45°. Find the measure of other two angles.
[Hint: Sum of the angles of a triangle is 180°]
​

Answer 1

Answer:

Let x = the measure of one of the two equal base angles; then the other angle mentioned must be x + 45. Therefore the total is x + x +(x+45) = 180 or 3x = 135.

Answer 2

Answer:

• Since it's a Right angled triangle, it has one of its angle as 90°
• 90°+45°+x=180°

x = 180°-(90°+45°)

x = 45°
