angle
In planar geometry, an angle is the figure formed by two rays, called the sides of the angle, sharing a common endpoint, called the vertex of the angle

right angle
In geometry and trigonometry, a right angle is an angle that bisects the angle formed by two adjacent parts of a straight line
Got it

congruent angles
In geometry, two figures or objects are congruent if they have the same shape and size, or if one has the same shape and size as the mirror image of the other
vertex
In geometry, a vertex is a point where two or more curves, lines, or edges meet
transversal
In geometry, a transversal is a line that passes through two lines in the same plane at two distinct points
perpendicular
In elementary geometry, the property of being perpendicular is the relationship between two lines which meet at a right angle
slope-intercept form
A linear equation is an algebraic equation in which each term is either a constant or the product of a constant and a single variable
compass
A compass is an instrument used for navigation and orientation that shows direction relative to the geographic "cardinal directions", or "points"
