See explanations on angles in an isosceles triangle
Step-by-step explanation:
5. ∠H=∠J⇒True, base angles of an isosceles triangle are equal
6. HK=KJ ⇒Trues, length of a line segments with same midpoint are equal
7.∠HKI=∠JKI ⇒True, both angles=90°
8.ΔHIK≅ΔJIH⇒False, the triangles are not similar,ΔHKI≅ΔJKI⇒True,the triangles are similar
9.IK is an altitude⇒True, an altitude of a triangle is a line segment drawn through a vertex I and perpendicular to a line containing the base HJ
10. IK is a median⇒True, a median of a triangle is a line segment joining a vertex to the midpoint of the opposite side hence bisecting that side.
