Angle types
What is an Angle?
The space between two intersecting lines or surfaces at or close to the point where they meet.
what is transversal?
A line that crosses at least two other lines
What is the basic formula of the Pythagorean theorem?
a² + b² = c²
What is Transformation?
A general term for any change in the position, size, or shape of a figure
what are Similar Figures
Figures that have the same shape but may have different sizes.
What are Complementary Angles?
Two angles that add up to 90 degrees.
What are Corresponding Angles?
Angles in the same position on two parallel lines cut by a transversal.
What is the Pythagorean Theorem
A formula that states the square of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides.
What is a Translation?
Moving a figure without rotating or flipping it.
what is a Similarity Statement
A statement that shows that two figures are similar, usually by showing corresponding angles are equal and sides are proportional.
What are Supplementary Angles?
Two angles that add up to 180 degrees.
What is Congruent?
Figures or angles that have the same size and shape (relevant to congruent triangles).
what is a Hypotenuse
The longest side of a right triangle, opposite the right angle.
what is a Reflection?
Flipping a figure over a line so it appears as a mirror image.
what is a proportion
An equation that shows two ratios are equal
What are Vertical Angles?
The opposite angles formed by two intersecting lines. They are always congruent.
What is Remote Interior Angle?
The angles inside a triangle that are not adjacent to a given exterior angle.
What are Legs
The two shorter sides of a right triangle.
What is Composition of Transformations?
Performing two or more transformations on a figure, one after the other.
What is a Scale Factor
The ratio of any two corresponding lengths in two similar geometric figures.
What are Alternate Exterior Angles?
Angles that are on opposite sides of the transversal and outside the two lines it crosses.
What is a Exterior Angle of a Triangle?
An angle formed by one side of a triangle and the extension of an adjacent side.
What are the 3 sides of the Pythagorean theorem?
a, b and c are the 3 sides
What is a Rotation?
Turning a figure around a point.
What is Dialation?
A transformation that enlarges or reduces a figure by a scale factor.
