Angles, Prisms, and Surface Area

The video tutorial introduces the concept of surface area for prisms, focusing on rectangular and triangular prisms. It reviews area formulas for rectangles, squares, and triangles, and applies these formulas to calculate the surface area of prisms. The tutorial includes problem-solving exercises to reinforce understanding of the concepts.

What is the defining characteristic of a prism?

• It has two identical bases.

• It has only one base.

• It is always a rectangular shape.

• It is always a triangular shape.

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

• Length times Width

• Side squared

• One half times Base times Height

• Base times Height

When calculating the surface area of a rectangular prism, what does the 'height' refer to?

• The diagonal length

• The up and down length

• The side that is parallel to the base

• The longest side of the prism

In a triangular prism, what are the lateral faces?

• The three rectangular sides

• The two triangular bases

• The top and bottom rectangles

• The diagonal faces

What is the formula for the surface area of a rectangular prism?

• 2(l + w + h)

• 2(lw + lh + wh)

• l + w + h

• lw + lh + wh

What is the hypotenuse in a right triangle?

• The longest side opposite the right angle

• The shortest side

• The side adjacent to the right angle

• The base of the triangle

Which type of angles add up to 90 degrees?

• Supplementary angles

• Vertical angles

• Complementary angles

• Adjacent angles

What is the sum of angles in a straight line?

• 360 degrees

• 180 degrees

• 90 degrees

• 270 degrees

What is the relationship between vertical angles?

• They are adjacent.

• They are equal.

• They are supplementary.

• They are complementary.

If two angles are complementary and one is 69 degrees, what is the other angle?

• 111 degrees

• 69 degrees

• 90 degrees

• 21 degrees
