Geometry: Measurement of Angles (Level 8 of 9)

The video tutorial covers solving problems involving inequalities in geometry, focusing on acute angles. It begins with determining restrictions on Angle B and variable X using inequalities. The tutorial then moves to solving for Y in terms of X by using congruent angles and algebraic expressions. The video emphasizes understanding inequalities and algebraic manipulation to solve geometric problems.

What is the range of degrees for an acute angle?

• Greater than 0 degrees and less than 90 degrees

• Greater than 90 degrees and less than 180 degrees

• Greater than 180 degrees and less than 360 degrees

• Greater than 0 degrees and less than 180 degrees

When solving inequalities, what must you remember to do when multiplying or dividing by a negative number?

• Subtract the same number from both sides

• Add the same number to both sides

• Flip the inequality symbol

• Keep the inequality symbol the same

What is the solution for X in the inequality 2X + 14 > 0?

• X < -7

• X > -7

• X > 7

• X < 7

If angle one is congruent to angle two, and the measure of angle one is X + 14, what is the measure of angle two if it is Y - 3?

• Y = X + 11

• Y = X + 17

• Y = X - 11

• Y = X - 17

What does it mean to solve for Y in terms of X?

• Express X as an equation involving Y

• Express Y as an equation involving X

• Find a specific value for X

• Find a specific value for Y
