3. Geometry Item 04-10 If AC = AE, then: A. Angles C and E are congruent by Isosceles Triangle Theorem ( If two sides of a triangle are congruent then the angles opposite those sides are congruent. ) Triangle ACE is isosceles because it has two congruent sides. www.upcatreview.com
4. Geometry Item 04-10 If AC = AE, then: B. Segment AD bisects CAE because in an isosceles triangle, the altitude of the bisects the vertex angle . Segment AD is an altitude because it is perpendicular to the base. www.upcatreview.com
5. Geometry Item 04-10 If AC = AE, then: C. Segment AD is a perpendicular bisector of Side CE because in an isosceles triangle, the altitude of the base bisects the base. Segment AD is both perpendicular to and a bisector of the base. www.upcatreview.com
