Triangles and Interest Calculations

The video tutorial covers drawing triangles using a protractor and compass, focusing on creating specific angles and lengths. It includes activities to draw triangles with given measurements and explores unique triangle configurations. The lesson concludes with a summary and homework solutions.

What tool is used to draw a 40° angle in the video?

• Ruler

• Set Square

• Protractor

• Compass

When drawing a triangle with a 40° angle and two sides of 5 cm, what is the length of the third side?

• 6 cm

• 3.5 cm

• 4 cm

• 5 cm

How many different triangles can be drawn with one angle of 40°, one side of 4 cm, and another side of 5 cm?

• One

• Two

• Three

• Four

What is the reason that only one triangle can be formed with two sides of 6 cm and an angle of 100°?

• The angle is too small.

• The sides are unequal.

• The angle is too large.

• The sides are too short.

What is the sum of the interior angles of a triangle?

• 270°

• 90°

• 360°

• 180°

Why can't a triangle have angles measuring 90°, 30°, and 100°?

• The angles are not distinct.

• The angles add up to more than 180°.

• The angles are too small.

• The angles are too large.

How many unique triangles can be drawn with side lengths of 7 cm, 4 cm, and 5 cm?

• None

• Three

• Two

• One

What is the interest earned on a $300 deposit at a 6% interest rate after one year?

• $18

• $30

• $12

• $6

If you leave $318 in an account with a 6% interest rate for another year, how much will you have?

• $350

• $318

• $337.08

• $336

What is the correct method to solve for x in the equation 3x = 9?

• Add 3 to both sides

• Multiply by 3

• Subtract 3 from both sides

• Divide by 3
