Question 1: What is a scalene triangle?

Answer:

A scalene triangle has no sides congruent.

Question 2: What does it mean to be coplanar?

Answer:

Coplanar figures are figures in the same plane.

Question 3: What is a rectangle?

Answer:

A rectangle is a parallelogram with four right angles.

Question 4: What is a right angle?

Answer:

A right angle is an angle whose measure is 90.

Question 5: What is the substitution property of equality?

Answer:

If a=b, then b can replace a in any expression.

Question 6: What is a square?

Answer:

A square is a parallelogram with four congruent sides and four right angles.

Question 7: What is a rotation?

Answer:

A rotation(turn) of a figure is a transformation.

Question 8: What is a trapezoid?

Answer:

A trapezoid is a quadrilateral with exactly one pair of parallel sides, the bases. the nonparallel sides are called the legs of a trapezoid. The altitude of a trapezoid is its height.

Question 9: What is an obtuse angle?

Answer:

An obtuse angle is an angle whose measure is between 90 and 180.

Question 10: What is a translation?

Answer:

A translation(slide) is a transformation that moves points the same distance and in the same direction. A translation in the coordinate plane is described by a vector.

Question 11: What is an angle of elevation?

Answer:

An angle of elevation is the angle formed by a horizontal line and the line of sight to an object above the horizontal line.

Question 12: What is a midpoint?

Answer:

A midpoint of a segment is the point that divides the segment into two congruent segments.

Question 13: What is a sector?

Answer:

A sector of a circle is the region bounded by two radii and their intercepted arc.

Question 14: What is a radius?

Answer:

A radius of a circle is any segment with one endpoint on the circle and the other endpoint at the center of the circle.

Question 15: What is a biconditional?

Answer:

A biconditional statement is the combination of a conditional statement and its converse. A biconditional contains the words "if and only if"

Question 16: What is a semicircle?

Answer:

A semicircle is half a circle and measures 180 degrees.

Question 17: What are vertical angles?

Answer:

Vertical angles are two angles whose sides form two pairs of opposite rays. They are congruent.

Question 18: What are supplementary angles?

Answer:

Two angles are supplementary angles if the sum of their measures is 180.

Question 19: What is a midsegment?

Answer:

In a trapezoid, a midsegment of a trapezoid is the segment that joins the midpoints of the nonparallel opposite sides of a trapezoid. In a triangle, the midsegment of a triangle is a segment that joins the midpoints of two sides of the triangle.

Question 20: What is an equilateral triangle?

Answer:

An equilateral triangle is a triangle whose sides are all congruent.

Question 21: What does the cosine ratio mean in trigonometry?

Answer:

The cosine ratio is leg adjacent/hypotenuse. On the Graping Calculator,cosine is abbreviated as "COS".

Question 22: What is the symmetric property of equality?

Answer:

If a=b, then b=a.

Question 23: What does the tangent ratio mean in trigonometry?

Answer:

The tangent ratio is leg opposite/leg adjacent. On the Graphing calculator, tangent is abbreviated as "TAN".

Question 24: What are complementary angles?

Answer:

Two angles are complementary angles if the sum of their measures is 90.

Question 25: What are collinear points?

Answer:

Collinear points are points that lie on the same line.

Question 26: What is the inverse of a conditional?

Answer:

The inverse of the conditional "if P, then Q" is the conditional "if not P, then not Q"

Question 27: What is a dilation?

Answer:

A dilation, or similarity transformation, is a transformation in which a figure gets larger or smaller by a certain scale factor.

Question 28: What is an angle of depression?

Answer:

An angle of depression is the angle formed by a horizontal line and the line of sight to an object below the horizontal line.
