geometry

4. angles Those angles that sum up to 180 degrees
6. A point where two or more curves, lines, or edges meet or intersect acute angle An angle smaller than the right angle
7. angle An angle larger than 90 degrees but less than 180 degrees right angle: An angle of exactly 90 degrees or 2 radians corresponding to a quarter turn adjacent Two angles are adjacent when they have a common vertex and a common side and don’t overlap

1. angles Formed when two lines meet each other at a point
2. A straight set of points that continue in opposite direction forever ray An end point followed by a sequence of points extending infinitely in one direction angle The figure formed by two rays, called the sides of the angle, sharing a common end point, called the vertex of the angle
3. Two shapes are congruent if they have sides of the same length and angles of the same measure
5. Coplaner infinite straight lines that do not intersect at any point Perpendicular: If there intersection forms right angles at the point of intersection called a foot
