Angles meet at a vertex whose plural is vertices
This is known in geometry as an interior angle.

In plane geometry, a shape with four sides, two of which are parallel and have the same length, cannot have a reflex angle.
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.
In geometry, an interior angle is an angle formed by two sides of a simple polygon that share an endpoint, namely, the angle of the inner side of the polygon.
In planar geometry, an angle is the figure formed by two rays, called the sides of the angle, sharing a common endpoint, called the vertex of the angle.
Chiliagon has 1000 sides. (In geometry, a chiliagon is a polygon with 1000 sides. The measure of each angle in a regular chiliagon is 179.64°.)
Pythagoras' theorem is an example of geometry in which for a right angle triangle the square of its hypotenuse is equal to the sum of the squares of its sides and the formula is:- a2+b2 = c2 whereas a and b are the sides of the right angle triangle with c being its hypotenuse or longest side
An attribute is a property or a description of something in geometry as for example a right angle triangle has the attributes of 3 sides and a 90 degree angle with 2 acute angles that add up to 90 degrees.
A Vertex is a point in simple language
The exterior angle of an octagon measures 45 degrees. In geometry, this belongs to the group of polygons which are composed of many sides and angles.
