Understanding Triangle Measurements

What is the relationship between the area of a rectangle and a triangle?

• A triangle's area is unrelated to a rectangle.

• A triangle's area is half that of a rectangle.

• A triangle's area is double that of a rectangle.

• A triangle's area is the same as a rectangle.

What is the first step in finding the area of a triangle?

• Identify the base and height.

• Calculate the perimeter.

• Draw a right angle.

• Measure the hypotenuse.

How can you measure the base of a triangle when no right angle is present?

• By measuring directly with a ruler.

• By using the formula for area.

• By guessing the length.

• By using a protractor.

What is a method to find the height of a triangle when it cannot be drawn inside?

• By drawing a horizontal line.

• By extending the base and drawing a vertical line.

• By using a compass.

• By measuring the hypotenuse.

Why might you need to extend the base of a triangle?

• To make the triangle larger.

• To calculate the perimeter.

• To find the height when it cannot be drawn inside.

• To measure the hypotenuse.

What is the significance of the highest point in a triangle?

• It is the shortest side.

• It is the midpoint of the base.

• It is the longest side.

• It is where the height is measured from.

What do tick marks on a triangle indicate?

• The sides with tick marks are equal in length.

• The triangle is isosceles.

• The triangle is equilateral.

• The triangle is right-angled.

What does it mean if a triangle has only one side length shown?

• The triangle is a right triangle.

• The triangle is an isosceles triangle.

• The other sides are equal to the shown side.

• The triangle is incomplete.

How does the orientation of a triangle affect its base and height?

• It does not affect the base and height.

• It changes the length of the base.

• It changes the length of the height.

• It changes the perception of which side is the base and height.

What should you do if the concept of triangle orientation is confusing?

• Ignore it.

• Practice more problems.

• Use the formula and let it sink in over time.

• Ask someone else to explain.
