Question

5 The
measurement of each angle of
right angled
isosceles triangle​

Answer 1

Answer:

Note that since the right triangle is isosceles, then the angles at the base are equal. (Theorem 3.) Therefore each of those acute angles is 45°.

Answer 2

Answer:

In geometry and trigonometry, a right angle is an angle of exactly 90° (degrees), corresponding to a quarter turn. If a ray is placed so that its endpoint is on a line and the adjacent angles are equal, then they are right angles.

isosceles, then the angles at the base are equal. Therefore each of those acute angles is 45°. (For the definition of measuring angles by "degrees,"
