Description
This example demonstrates how to calculate the area of an acute triangle. The triangle has angles labeled as 50° and 60°, with a base measuring 12 units and a height of 8 units. To find the area, we use the formula A = 1/2 * b * h. In this case, A = 1/2 * 12 * 8 = 48 square units.
Understanding the area of triangles is a fundamental concept in geometry that applies to various real-world situations. This collection of examples helps students visualize different types of triangles and compute their areas accurately using given dimensions.
Exposure to multiple worked-out examples is crucial for students to fully grasp these concepts as each example reinforces fundamental principles while introducing new approaches for calculating areas based on different types of triangles.
Teacher Script: "Let's examine this acute triangle with angles labeled as such because they are less than right angles (90°). We have a base length (12) & corresponding perpendicular height (8). Using our formula A=½bh gives us an answer—48 sq.units! Can you think about where else you might see or use acute-angled triangles?"
