When do we need ½absinC?
A matching activity to reinforce when to use trigonometry to find the area of a triangle with A=1/2absinC.
Students match each triangle with the workings needed to find the area and the final answer.
Encourages students to show workings and think about different approaches to solve the same problem.

Students thought it would be really easy but I love how mixed the cahllenge between the normal formula of perpendicular heights and the trigonometric one. Love it!
Thank you!
