1. Exploring
Quadrilaterals

2. A quadrilateral is a closed geometric figure with four sides and four
vertices. The sides of a quadrilateral intersect only at their endpoints.

4. Sides, Angles and Vertices of a Quadrilaterals
Sides:
𝐴𝐵, 𝐵𝐶, 𝐷𝐶 and 𝐴𝐷
Angles:
= ∠𝐷𝐴𝐵 or ∠𝐵𝐴𝐷 or ∠𝐴
= ∠𝐴𝐵𝐶 or ∠𝐶𝐵𝐴 or ∠B
= ∠𝐵𝐶𝐷 or ∠𝐷𝐶𝐵 or ∠𝐶
= ∠𝐴𝐷𝐶 or ∠𝐶𝐷𝐴 or ∠𝐷
Vertices (Vertex):
vertex A, B, C and D

5. Opposite Sides, Angles and Vertices of a
Quadrilaterals
Opposite Sides:
𝐴𝐵 and 𝐷𝐶, 𝐴𝐷 and 𝐵𝐶
Opposite Angles:
∠𝐵𝐴𝐷 and ∠𝐵𝐶𝐷, ∠𝐴𝐵𝐶 and ∠𝐶𝐷𝐴
Opposite Vertices:
vertex A and vertex C, vertex B and
vertex D

6. Consecutive Sides, Angles and Vertices of a
Quadrilaterals
Consecutive Sides:
AB and BC, AB and AD
BC and CD, CD and DA
Consecutive Angles:
∠𝐷𝐴𝐵 and ∠𝐴𝐵𝐶, ∠𝐴𝐵𝐶 and ∠𝐵𝐶𝐷
∠𝐵𝐶𝐷 and ∠𝐶𝐷𝐴, ∠𝐶𝐷𝐴 and ∠𝐷𝐴𝐵
Consecutive Vertices:
vertex A and vertex B, vertex B and vertex C
vertex C and vertex D, vertex D and vertex A

7. Name the opposite sides, angles and vertices.

8. Identify whether consecutive / opposite sides,
angles or vertex.
