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

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°.
