## Measurement: Triangle Base and Height

#### 1. Identifying the base and height of a triangle.

**What is a base?**

Base means bottom.

**What is height?**

The height of any object is how much it measures from its top to its bottom.

**How do you identify the base of a triangle?**

Any of the three sides of a triangle can be considered the base of the triangle.

**How do you identify the height of a triangle?**

The height of a triangle is the perpendicular line dropped onto its base from the corner opposite the base.

**Notes:**

- The height of a triangle corresponds to its base. If the base changes, so does the height.
- The height of a triangle is the shortest line onto the base from its opposite corner.
- The height of a triangle may be outside the triangle.
