Examples, solutions, videos, and worksheets to help Geometry students learn how to solve for unknown angles involving lines and angles at a point, angles involving transversals, and angles in triangles.
To find angles involving triangles and transversals, you can use geometric rules like the Triangle Angle Sum Theorem, the Exterior Angle Theorem, and the properties of angles formed by transversals intersecting parallel lines.
Key Angle Relationships:
Corresponding Angles: These angles are equal in measure.
Alternate Interior Angles: These angles are equal in measure.
Alternate Exterior Angles: These angles are equal in measure.
Same-Side Interior Angles: These angles are supplementary (they add up to 180 degrees).
Angles in a Triangle: The sum of the angles in a triangle is 180 degrees.
Exterior Angle Theorem: An exterior angle of a triangle is equal to the sum of the two opposite interior angles
