What is side side side angle?
The SAS (Side-Angle-Side) postulate states that if two sides and the included angle of one triangle are congruent to two sides and the included angle of another triangle, then the triangles are congruent.
What is angle side angle in geometry?
The Angle-Side-Angle Postulate (ASA) states that if two angles and the included side of one triangle are congruent to two angles and the included side of another triangle, then the two triangles are congruent.
What is the definition of lines and angles?
In geometry, lines and angles are the basic terms that set up the foundation for the subject. A line is defined as a row of closely spaced dots that extends infinitely in two directions. An angle is defined as a figure created by two rays that meet at a common endpoint. They are measured in degrees, using a protractor.
What is an example of side angle side?
Side angle side postulate ->If two sides and the included angle of a triangle are congruent to two sides and the included angle of another triangle, then the two triangles are congruent by side angle side postulate….Side Angle Side Postulate.

6) CE || AB | 6) If alternate interior angles are congruent then the lines are parallel |
How do you calculate side angle side?
“SAS” is when we know two sides and the angle between them. use The Law of Cosines to calculate the unknown side, then use The Law of Sines to find the smaller of the other two angles, and then use the three angles add to 180° to find the last angle.
What is the side-angle-side similarity theorem?
If an angle of a triangle is congruent to an angle of another triangle and if the included sides of these angles are proportional, then the two triangles are similar .
What are lines in math?
A line is a one-dimensional figure, which has length but no width. A line is made of a set of points which is extended in opposite directions infinitely. It is determined by two points in a two-dimensional plane. The two points which lie on the same line are said to be collinear points.
What are lines Class 9?
(i) If a ray stands on a line, then the sum of two adjacent angles so formed is 180°. (ii) If the sum of two adjacent angles is 180°, then a ray stands on a line (that is the non-common arms form a line). ∠AOC + ∠BOC = 180° Property: If two lines intersect each other, then the vertically opposite angles are equal.
