Interior angles are those that lie inside a polygon. For example, a triangle has 3 interior angles. The other way to define interior angles is "angles enclosed in the interior region of two parallel lines when intersected by a transversal are known as interior angles".

14 cze 2023 · Angles that are found inside or within any geometric shape are called interior angles. They are also sometimes called internal angles. A triangle has three interior angles. Similarly a quadrilateral such as a square, rectangle, parallelogram, kite, or a trapezoid has four interior angles.
An Interior Angle is an angle inside a shape: Another example: Triangles. The Interior Angles of a Triangle add up to 180°
Alternate Interior Angles: These angles are congruent angles located between the parallel lines in the interior region and on opposite sides of the transversal & at different vertices.
Interior angles are all the angles found inside a shape, in this case a triangle (which means we are working with 3 interior angles). The sum of the interior angles is always 180 degrees.
Interior and exterior angles worksheet will help students in building upon clear concepts with angles in geometry. The angles within a geometrical figure are termed interior while outside of the figure are called exterior angle.
Interior angles: Interior Angles are the angles formed within or inside a shape. Here, ∠ABC, ∠BCA and ∠CAB are interior angles. Exterior angles: Exterior angles are the angles formed outside a shape, between any side of a shape and an extended adjacent side.
