Triangle Area and Properties

The video tutorial explains how to determine the base, height, and area of a triangle on a grid. It starts by identifying the base and height using the grid's measurements, then calculates the area using the formula (base * height) / 2. The tutorial also explains the derivation of the area formula by comparing the triangle to a parallelogram.

What is the side length of each small square on the grid?

• 0.5 meters

Which side of the triangle is typically considered the base?

• The bottom side

• The side parallel to the grid

• The longest side

• The side with the smallest angle

How long is the base of the triangle in meters?

• 10 meters

• 9 meters

• 11 meters

• 8 meters

What is the height of the triangle in meters?

• 5 meters
