Free Grade 6 Area of Triangles and Parallelograms Practice

Students will understand and apply formulas to find the area of triangles and parallelograms, including decomposing and rearranging shapes.

Topic Overview

Definitive Answer: Students will understand and apply formulas to find the area of triangles and parallelograms, including decomposing and rearranging shapes.

Imagine you're building something, like a mini-house. Before you can figure out how much paint you need for a wall, you need to know its length and how tall it is. In geometry, we have similar important measurements called the **base** and **height** for shapes like parallelograms and triangles. The **base** is any side you choose to start measuring from. The **height** is the straight, **perpendicular** distance from that base to the opposite side (for a parallelogram) or the opposite corner (vertex) (for a triangle). 'Perpendicular' means forming a perfect 90-degree angle, like the corner of a square. Knowing these helps us understand how much space a shape covers.

Step-by-Step Examples

Example 1: Picture a parallelogram, like a leaning rectangle. It has four sides. Let's label the bottom side as 'AB', the top side as 'CD', and the slanted sides as 'BC' and 'DA'. If we choose side AB as our base, describe how to find its corresponding height.
  1. First, identify side AB as the chosen base.
  2. Next, imagine a straight line drawn from side AB up to side CD, making sure this line forms a perfect 90-degree angle (is perpendicular) with both AB and CD. This perpendicular distance is the height.
✓ Answer: The base is side AB. The height is the perpendicular distance between side AB and side CD.
Example 2: Now, imagine a triangle with vertices labeled P, Q, and R. If we choose side QR as our base, describe how to find its corresponding height.
  1. First, identify side QR as the chosen base.
  2. Next, imagine a straight line drawn from the vertex P (the corner opposite the base QR) down to the line containing side QR, making sure this line forms a perfect 90-degree angle (is perpendicular) with QR. This perpendicular distance is the height.
✓ Answer: The base is side QR. The height is the perpendicular distance from vertex P to side QR.

Tips & Tricks

  • Remember, the 'H' in Height stands for 'How high?' and it always needs to be 'Perpendicular' – like standing up straight!

Key Vocabulary

TermDefinition
BaseAny side of a parallelogram or triangle chosen as the reference for measuring height.
