M2 Unit 6 Vocabulary

What is the hypotenuse?

• The longest side of a triangle opposite the right angle.

• The shortest side of a triangle adjacent to the right angle.

• The side opposite the acute angle in a triangle.

• The side opposite the right angle.

What is the side-splitter theorem?

• The side-splitter theorem states that if a line intersects two sides of a triangle and is parallel to the third side of the triangle, it divides those two sides proportionally.

• The side-splitter theorem states that the angles opposite to equal sides of a triangle are equal.

• The side-splitter theorem states that the sum of the lengths of any two sides of a triangle is greater than the length of the third side.

• The side-splitter theorem states that the area of a triangle is equal to half the product of its base and height.

What is a reflection in geometry?

• A transformation that rotates a figure around a point.

• A transformation that flips a figure over a line, creating a mirror image of the original figure.

• A transformation that enlarges or reduces a figure proportionally.

• A transformation that translates a figure to a different location without changing its shape.

What does collinear mean?

• Collinear is when three or more points lie in a line.

• Collinear refers to points that are equidistant from each other.

• Collinear means that points form a triangle.

• Collinear indicates that points are located in different planes.

What are alternate exterior angles?

• A pair of angles formed by a transversal intersecting two lines that lie outside of the two lines and are on opposite sides of the transversal.

• Angles that are formed inside the two lines by a transversal.

• Angles that are equal in measure and lie on the same side of the transversal.

• A pair of angles that are adjacent to each other and formed by a transversal.

What is a transversal?

• A line that passes across two or more other lines in the same plane at different points.

• A type of angle formed when two lines intersect.

• A line that is parallel to another line in the same plane.

• A line that divides a shape into two equal parts.

What is a proportion?

• A proportion is a statement that two ratios are equal.

• A proportion is a type of fraction.

• A proportion is a mathematical operation involving addition.

• A proportion is a comparison of two different quantities.

What is a center of dilation?

• A point where all lines intersect in a geometric figure.

• A fixed point around which a geometric figure is enlarged or shrunk during a dilation transformation.

• The midpoint of a line segment in a geometric figure.

• A point that represents the origin of a coordinate system.

What is a geometric transformation?

• An operation that moves or changes a geometric figure to produce a new figure.

• A method to calculate the area of geometric shapes.

• A technique used to draw geometric figures accurately.

• A process of measuring angles in geometric figures.

What is a translation in geometry?

• A type of transformation that rotates a figure around a point.

• A type of transformation that slides a figure in a straight line from one position to another without turning or flipping it.

• A type of transformation that enlarges or reduces a figure in size.

• A type of transformation that reflects a figure over a line.
