What does it mean for a side or angle to be included?
The 'included side' is the side between the two given angles. The 'included angle' is the angle between the two given sides.
What is the angle-angle-side rule?
Side-Angle-Side is a rule used in geometry to prove triangles congruent. The rule states that if two sides and the included angle are congruent to two sides and the included angle of a second triangle, the two triangles are congruent. An included angle is an angle created by two sides of a triangle.
What makes a quadrilateral unique?
4 sides and 1 diagonal is given. 3 sides and 2 diagonals are given. 3 angles and measurement of two adjacent angles are given. 3 sides and 2 included angles are given. 4 sides and 1 angle is given.
What is the point that two sides of a polygon have in common?
Any two adjacent sides on a polygon will form an included angle.
What is the difference between angle side angle and angle angle side?
The first is two angles and the included side whereas the second is two sides and the included angle!
