If two acute angles of a right triang...

If two acute angles of a right triangle are equal, then each acute is equal to `30^0` (b) `45^0` (c) `60^0` (d) `90^0`

Text Solution

Verified by Experts

Let the angles of the triangle be 1, 2 and 3.
/_1 = 90@ and /_2 = /_3
We know that, the sum of three angles of a triangle is 180@ :
/_1 + /_2 + /_3 = 180@
90° + /_2 + /_2 = 180@
2/_2 = 180° – 90@
2/_2 = 90@
/_2 = 90@/2
/_2 = 45@
Therefore, /_2 = /_3 = 45@'.
