Question

1.4.8Danielle tests the following conjecture.If two angles share a common vertex, then they are adjacent.Her work is shown to the right. What error does Danielle make?Choose the correct answer below.

Answer 1

Step-by-step explanation:

The diagram drawn shows two angles that share a common side and a common vertex.

Danielle only mentioned two angles share a common vertex in her conjecture.

Hence, the statement is false as there are angles which share a common vertex and they are not adjacent angles. These angles are called vertical angles.

Adjacent angles have both a common vertex and side.

Hence, Danielle ony gave an example of angles that share a vertex
