CCSS.6.G.A.1

True or False? Any side of a triangle can be the base side.

• True--it doesn't have to be the bottom side in the orientation of the triangle. You can turn the triangle until the base is the bottom if you want.

• False--the base can only be the side on the bottom.

We know we can use ANY triangle side as the base, so long as we have a height marked perpendicular (at a right angle) to it.

Which side would be the best to use as the base of the triangle, because it's connected to the height by a right angle?

• 18 cm

• 14 cm

• 8 cm

• 6 cm

What is the area of this triangle?

Remember that base and height come at a right angle, and the base does NOT need to be at the bottom.

You can always turn the triangle if it helps to see the base at the bottom.

• 14 units²

• 24 units²

• 48 units²

• 20 units²
