Quadrilaterals have 4 sides, and triangles have 3 sides. So, you simply have to count the number of sides.

Triangles are anything with three vertexes and three angles to it and are always closed.

Quadrilaterals are anything with four vertexes and four angles on them and are always closed.  Examples include a square, rectangle, trapezoid etc.

vodka [1.7K]

Answer:    49°, 49°, 82°

<u>Step-by-step explanation:</u>

Let x represent the base angles

then 2x - 16 is the vertex angle.

Triangle Sum Theorem states that the sum of the angles is 180°

(x) + (x) + (2x - 16) = 180

                 4x - 16 = 180

                       4x = 196

                         x = 49

Base angles: x = 49

Vertex angle: 2(49) - 16 = 82
