Angles, Triangles, and Prisms Concepts

This video tutorial covers angles, triangles, and prisms. Students learn about angle relationships, such as complementary and supplementary angles, and how to determine unique or multiple triangles based on given measurements. The video also explains how to calculate the surface area and volume of prisms, using a triangular prism as an example.

What is the main focus of the video on angles, triangles, and prisms?

• To investigate the determination of triangles using angles and side lengths

• To study the properties of circles

• To explore the history of geometry

• To learn about the life of famous mathematicians

Which of the following is NOT an essential vocabulary word introduced in the unit?

• Complementary angles

• Adjacent angles

• Vertical angles

• Parallel lines

What is the sum of two complementary angles?

• 45 degrees

• 90 degrees

• 180 degrees

• 360 degrees

If two angles add up to 180 degrees, what are they called?

• Complementary angles

• Vertical angles

• Supplementary angles

• Adjacent angles

What is true about vertical angles?

• They are always complementary

• It forms a unique triangle

How many identical copies of a triangle can be drawn with two sides of 3 units and an angle of 60 degrees?

• None

• One

• Three

• Two

What is the base shape of the triangular prism discussed in the video?

• Rectangle

• Square

• Equilateral triangle

• Right triangle

How is the volume of a prism generally calculated?

• By adding the areas of all faces

• By multiplying the area of its base by its height

• By subtracting the area of its base from its height

• By dividing the area of its base by its height

What is the total surface area of the example prism in the video?

• 718 square inches

• 600 square inches

• 800 square inches

• 500 square inches
