PRESENTATION OUTLINE
ACUTE ANGLE :
- an angle with a measure greater than 0 degrees and less than 90 degrees .
OBTUSE ANGLE :
- an angle greater than 90 degrees but less than 180 degrees .
RIGHT ANGLE :
- the angle formed by two radii of a circle that are drawn to the extremities of an arc equal to one quarter of the circle; the angle formed by two perpendicular lines that intersect; an angle of 90°.
STRAIGHT ANGLE :
- the angle formed by two radii of a circle that are drawn to the extremities of an arc equal to one half of the circle; an angle of 180°.
VERTICAL ANGLE :
ONE OF TWO OPPOSITE AND EQUAL ANGLES FORMED BY THE INTERSECTION OF TWO LINES .
ADJACENT ANGLE :
two angles having the same vertex and having a common side between them .
SUPPLEMENTARY :
EITHER OF TWO ANGLES THAT ADDED TOGETHER PRODUCE AN ANGLE OF 180°.
CORRESPONDING ANGLE :
TWO NONADJACENT ANGLES MADE BY THE CROSSING OF TWO LINES BY A THIRD LINE, ONE ANGLE BEING INTERIOR, THE OTHER EXTERIOR, AND BOTH BEING ON THE SAME SIDE OF THE THIRD LINE .
TRANSVERSAL :
THE THIRD LINE FORMED WHEN TWO PARALLEL LINES ARE INTERSECTED
COMPLEMENTARY :
TWO ANGLES ARE COMPLEMENTARY IF THE SUM OF THEIR MEASURES IS 90 DEGREESSSSSES .
