The video tutorial focuses on applying the formula for the area of triangles. It begins with an introduction to the activity, followed by instructions on how to find the area of triangles using the base and height. An example calculation is demonstrated with triangle A. The video discusses the importance of correctly identifying the base and height, and analyzes the measurements of triangles C, D, and E. It concludes with a discussion on the unique properties of right triangles.

What is the formula used to calculate the area of a triangle?

• Base plus height

• Base plus height divided by two

• Base times height divided by two

• Base times height

What should you do before returning to the video after attempting to find the area of triangles?

• Check the answers online

• Rewatch the video

• Discuss with a partner

• Skip to the next section

In the example calculation, what were the base and height measurements used?

• 6 cm and 5 cm

• 5 cm and 7 cm

• 7 cm and 6 cm

• 5 cm and 6 cm

Why can't the height be used as the base in a triangle?

• The height is always shorter

• The base must be a side of the triangle

• The height is not a measurement

• The base is always longer

For triangle C, why is the 3 cm piece not suitable as a base?

• It is not a side of the triangle

• It is too short

• It is not labeled

• It is not perpendicular

What makes right triangles like B and D unique when finding their area?

• They have equal sides

• They have no height

• They have a 90-degree angle

• They have more than two measurements

Which measurement is more useful for finding the area of triangle C?

• 7 cm

• 5 cm

• 3 cm

• 3.5 cm

Why is it important to identify matching base and height in triangles?

• To determine the type of triangle

• To ensure the triangle is right-angled

• To accurately calculate the area

• To find the perimeter

What should you do if your calculated area does not make sense?

• Check if the base and height are correctly identified

• Recalculate using a different formula

• Ignore the result

• Use a calculator

Which two measurements are typically useful for finding the area of a triangle?

• Any two sides

• Base and hypotenuse

• Base and height

• Height and hypotenuse
