Triangle Ratios and Pythagorean Theorem

The video tutorial covers ADA compliance for ramps, focusing on the required angle and ratio standards. It explains how to find missing side lengths in triangles using the Pythagorean theorem and proportions. The tutorial also guides on designing ADA-compliant ramps and using mirrors for indirect height measurement. It discusses estimating lengths using Pythagorean triples and determining triangle similarity through angle comparison.

What is the maximum angle allowed for a ramp to comply with ADA regulations?

• 4.5 degrees

• 6.0 degrees

• 5.0 degrees

• 4.8 degrees

What is the ratio of height to length that a ramp must not exceed according to ADA standards?

• 1:10

• 1:12

• 1:15

• 1:8

If a triangle has a ratio of 1:12, is it ADA compliant?

• Only if the length is more than 12 units

• Only if the angle is less than 4.8 degrees

• No

• Yes

Which triangle ratio indicates a non-compliant ADA ramp?

• 1:10

• 2:15

• 1:15

• 1:12

What method can be used to find a missing side length in a right triangle?

• Graphical estimation

• Trigonometry

• Pythagorean theorem

• Algebraic substitution

How can you verify your answer after finding a missing side length in a triangle?

• Guessing

• Using a different method

• Recalculating the same way

• Asking a friend

What is the scale factor if a triangle's sides are doubled?

• 2

• 1.5

• 3

What is the minimum length required for a ramp that is 1 yard high to be ADA compliant?

• 10 yards

• 12 yards

• 13 yards

• 15 yards

If a ramp is 3 feet tall, what is the minimum length it must be to comply with ADA standards?

• 45 feet

• 30 feet

• 40 feet

• 36 feet

What is the decimal equivalent of the ratio 3:40?

• 0.150

• 0.125
