Question

abc is an isosceles triangle right angled at b . if so find all the angles.

Answer 1

Answer:

All angles- 90°,45°,45°.

Step-by-step explanation:

We are given that it is right-angled triangle. So, one angle would be of 90°. And, it is also told that it is an isosceles triangle so the two sides are equal. By this the two angles would be also equal as by the statement- 'angles opposite to equal sides are equal'. Now, by angles sum property the sum of all angles is 180°. From them, one is of 90°, so the sum of other two will be 180°-90°= 90°. And also, both are equal, so each would be of 45°.
