What are the angle relationships with Transversals?

If a transversal intersects two parallel lines, then each pair of interior angles on the same side of the transversal is supplementary, i.e. they add up to 180° . When two lines intersect each other, then the opposite angles, formed due to intersection, are called vertical angles or vertically opposite angles.

What is the relationship between the angles of each triangle?

Side-Angle Relationship: In triangles, the shortest side is always opposite the smallest angle; the longest side is always opposite the largest angle . Conversely, the smallest angle is always opposite the shortest side, and the largest angle is always opposite the longest side.

What is the rule of angles in triangle?

The angles in any triangle add to 180° . The angles in any quadrilateral add to 360°. The angles in any polygon with 𝑛 sides add to (𝑛 − 2) × 180°.

How do you find the relationship between triangles?

Two triangles are similar if they meet one of the following criteria. : Two pairs of corresponding angles are equal . : Three pairs of corresponding sides are proportional. : Two pairs of corresponding sides are proportional and the corresponding angles between them are equal.

How do you know the relationship between the two triangles?

Two triangles are said to be similar if their corresponding angles are congruent and the corresponding sides are in proportion . In other words, similar triangles are the same shape, but not necessarily the same size. The triangles are congruent if, in addition to this, their corresponding sides are of equal length.

What are the 7 types of triangles?

The six types of triangles are: isosceles, equilateral, scalene, obtuse, acute, and right .

What is the rule of a transversal?

1. If a transversal cuts two parallel lines, each pair of corresponding angles are equal in measure . 2. If a transversal cuts two parallel lines, each pair of alternate interior angles are equal.

How do transversals work?

Parallel lines are lines in the same plane that go in the same direction and never intersect. When a third line, called a transversal, crosses these parallel lines, it creates angles . Some angles are equal, like vertical angles (opposite angles) and corresponding angles (same position at each intersection).

What is the relationship of angles formed by a transversal?

If two parallel lines are cut by a transversal, then the pairs of consecutive interior angles formed are supplementary . When two lines are cut by a transversal, the pairs of angles on either side of the transversal and inside the two lines are called the alternate interior angles .

What are the angles on the same transversal?

The interior Angles that lie on the same side of the transversal are known as co – interior angles . The sum of these angles is 180°. In other words, these angles are supplementary. Also, the sum of the co – interior angles will only be 180° if the lines are parallel.

What are corresponding angles in Transversals?

Corresponding angles are formed when a transversal intersects two parallel lines . These angles are located on the same side of the transversal in corresponding positions. Corresponding angles are always formed in pairs and are congruent.
