6110math Support for teachers and parents 6th Grade Illustrative Math Unit 1 Lesson 10 Bases and Heights of Triangles Review and Tutorial Search Using the area formula to find height The formula for the area of a triangle is frac 1 2 base times height 21 base height or frac 1 2 bh 21bh If you know the area and the length of a base then you can calculate the height A frac 1 2 bh A
Show your reasoning Lesson 10 Summary A height of a triangle is a perpendicular segment between the side chosen as the base and the opposite vertex We can use tools with right angles to help us draw height segments An index card or any stiff paper with a right angle is a handy tool for drawing a line that is perpendicular to another line INTRODUCING Using Area to Find the Height The area formula for a triangle is A 1 2 bh After rearranging the formula to isolate h we end up with h 2A b If we have the area and base we simply plug them into this new formula to find height Example Problem Find the height of a triangle with a base of 10 and an area of 20 Solution
