Adjective angles	adjacent angles. two angles having the same vertex and having a common side between them
Corresponding angles	the angles which occupy the same relative position at each intersection where a straight line crosses two others. If the two lines are parallel, the corresponding angles are equal
Alternative angles	Alternate Interior Angles. When two lines are crossed by another line (called the Transversal): The pairs of angles on opposite sides of the transversal but inside the two lines are called Alternate Interior Angles
Acuate angles	An acute angle ("acute" meaning "sharp") is an angle smaller than a right angle (it is less than 90 degrees and more than 0 degrees).If you choose the larger angle you. ... The smaller angle is an Acute Angle, but the larger angle is a Reflex Angle. Acute angles are the smallest types of angles
Right angles	an angle of 90°, as in a corner of a square, or formed by dividing a circle into quarters.
Obtuse angles	An obtuse angle is any angle larger than 90 degrees. In other words, if the angle formed where two line segments meet goes beyond a right angle, it's obtuse.
Complementary angles	either of two angles whose sum is 90°.
Vertical angles	each of the pairs of opposite angles made by two intersecting lines.
Angles around a point	Angles around a point will always add up to 360 degrees. Because of this, we can find an unknown angle
Sum of angles inside a triangle	In a Euclidean space, the sum of measures of these three angles of any triangle is invariably equal to the straight angle, also expressed as 180°, π radians, two right angles, or a half-turn
Base of angles of an isosceles	In isosceles triangle RST, angle S is the vertex angle. Base angles R and T both measure 64 degrees
Supplementary angles add up to	Two Angles are Supplementary when they add up to 180 degrees. Notice that together they make a straight angle. But the angles don't have to be together.
Co- interior angles always add up to	When two lines are cut by a third line (transversal) co-interior angles are between the pair of lines on the same side of the transversal. If the lines are parallel the co-interior angles are supplementary (add up to 180 degrees)
The exterior angle of a triangle is always equal to the	An exterior angle of a triangle is equal to the sum of the opposite interior angles. For more on this see Triangle external angle theorem. If the equivalent angle is taken at each vertex, the exterior angles always add to 360° In fact, this is true for any convex polygon, not just triangles
An isosceles triangle has_____ sides equal
An equilateral triangle has slates equal	In geometry, an equilateral triangle is a triangle in which all three sides are equal. In the familiar Euclidean geometry,equilateral triangles are also equiangular; that is, all three internal angles are also congruent to each other and are each 60
Straight angle	an angle of 180 degrees
Reflex angle	The reflex angle is the larger angle. It is more than 180 degrees but less than 360 degrees If you choose the smaller angle you might have an Acute Angle, or an Obtuse Angle instead: The larger angle is a Reflex Angle, but the smaller angle is an Acute Angle.
Revaluation angle	Revolution. more ... A 360 degree angle, a full rotation, a complete turn so it points back the same way.
