Answer» ong>Step-by-step explanation: SINCE,one angle is given RIGHT ANGLED = 90° & it is an isosceles triangle so 2 opp. angles are EQUAL = 45° Alternative : Since, Sum of the angles of a triangle is 180°, One angle is given 90° So, the sum of other 2 angles must be 90° Therefore, as one angle is 45° and so the other angle is also 45°.

ong>Step-by-step explanation:

SINCE,one angle is given RIGHT ANGLED = 90°

& it is an isosceles triangle so 2 opp. angles are EQUAL = 45°

Alternative :

Since, Sum of the angles of a triangle is 180°,

One angle is given 90°

So, the sum of other 2 angles must be 90°

Therefore, as one angle is 45° and so the other angle is also 45°.
