The parts of triangles which are congruent is ∠A ≅ ∠E which is option (C)
What is congruent triangle?
- In geometry, two figures or objects are congruent if they have the same shape and size, or if one has the same shape and size as the mirror image of the other
- Congruent triangles are triangles that have the same size and shape.
- This means that the corresponding sides are equal and the corresponding angles are equal.
- We can tell whether two triangles are congruent without testing all the sides and all the angles of the two triangles.
How to solve this problem?
The steps are as follow:
- As ACE is a straight line which connects to line AB and DE
- Also the line AB and ED are parallel because their gradient are same
- So from above mention two reasons we can say that their is congruence between angle A and angle E
So the parts of triangles which are congruent is ∠A ≅ ∠E which is option (C)
