Right Triangle Concepts and Calculations

This video tutorial explains how to determine the length of a missing side in a right triangle using the Pythagorean theorem. It then guides viewers through calculating the perimeter and area of the triangle, rounding results to the nearest hundredth. The tutorial emphasizes the use of a calculator for precise calculations and verifies results to ensure accuracy.

What is the first step in solving for the missing side of a right triangle?

• Identify the hypotenuse

• Find the perimeter

• Use the Pythagorean theorem

• Calculate the area

In a right triangle, which side is opposite the right angle?

• Leg a

• Leg b

• Base

• Hypotenuse

What equation represents the Pythagorean theorem?

• a + b = c

• a^2 + b^2 = c^2

• a^2 - b^2 = c^2

• a^2 + b = c^2

After calculating x^2 = 112, what is the next step to find x?

• Multiply both sides by 2

• Take the square root of both sides

• Subtract 112 from both sides

• Add 112 to both sides

What is the approximate length of the missing side of the triangle?

• 10.58 cm

• 16 cm

• 14 cm

• 12 cm

How do you calculate the perimeter of a triangle?

• Add all side lengths together

• Multiply all side lengths

• Divide the hypotenuse by two

• Subtract the smallest side from the largest

What is the perimeter of the triangle with sides 10.58 cm, 12 cm, and 16 cm?

• 38.58 cm

• 35 cm

• 40 cm

• 30.58 cm

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

• Base minus height

• One-half base times height

• Base plus height

• Base times height

What is the approximate area of the triangle?

• 60 square cm

• 63.48 square cm

• 65 square cm

• 70 square cm

Why is the approximate symbol used in the area calculation?

• The base is an estimate

• The height is rounded

• The hypotenuse is unknown

• The perimeter is not exact
