Area, Right Triangle: T-Chart

The video tutorial explains how to calculate the area of right triangles using the formula 1/2 times base times height. It introduces the concept of area and its dependence on shape type, focusing on right triangles. The tutorial demonstrates using an AT chart to organize information and a T chart to explain the calculation process. It provides examples with different measurements and emphasizes the importance of stating the area in square units. The video encourages practice with these methods to enhance understanding.

What is the formula for finding the area of a right triangle?

• Base minus height

• Base times height

• 1/2 times base times height

• Base plus height

In the example provided, what is the base of the right triangle?

• 4 centimeters

• 8 centimeters

• 2 centimeters

• 5 centimeters

What is the purpose of using an AT chart when calculating the area of a triangle?

• To draw the triangle

• To organize information and calculations

• To measure the triangle

• To find the perimeter

When using the T chart method, what is the first step in finding the area of a right triangle?

• State the area in square units

• Substitute the values

• Write the formula

• Multiply the base and height

In the second example, what is the area of the right triangle with a base of 5 inches and a height of 8 inches?

• 10 inches squared

• 20 inches squared

• 40 inches squared

• 30 inches squared
