Question

ABC is a right angle triangle in which LA equal to 90 degree and AB equal to AC find LA AND LB​

Answer 1

Answer:

45° each

Step-by-step explanation:

As AB=AC this means ∆ABC is a right angle isosceles triangle.

Therefore angle B= angle C (angles opposite to equal lines are equal)

angleA+ angleB+ angleC = 180° (angle sum property)

angle A = 90°

angle B= angle C (as discussed above)

therefore,

90°+ angle B+ angle B= 180°

angle B= 45°

therefore, angle B and angle C= 45° each.
