Question

question 6: 418641

a (angle h=angle j)
b (angle i=angle j)
c (angle i=angle h)
d cannot be determined
question 7: 418640

Explanation:

Step1: Recall the property of isosceles triangle

In an isosceles triangle, the angles opposite the equal sides are congruent.

Step2: Identify the equal sides and their opposite angles

In triangle \(IJH\), the sides \(IJ\) and \(JH\) are equal (marked with the same tick). The angle opposite \(IJ\) is \(\angle H\) and the angle opposite \(JH\) is \(\angle I\).

Answer:

C. \(\angle I\cong\angle H\)
