Rectangle is a polygon (A close plane figure which has 3 or more sides)
Rectangle is a parallelogram (Opp Sides are parallel and congruent)
Rectangle has 4 right (90 degrees) angles, 4 sides and vertices (Corners).
Just saying a square is a type of rectangle and rhombus (4 Congruent sides)
Search about Quadrilaterals. Glad I could help!

Answer:
A triangle with two angles of the same size is an isosceles triangle. So two of its sides are going to have the same measure and the third different. The length of the sides will depend on the height of the measure of the given angles.
Step-by-step explanation:
Isosceles triangles can be classified into an isosceles right triangle, isosceles obtuse, isosceles acute depending on the measurements of its internal angles.
Answer:
third option is the correct
Step-by-step explanation:
A function is "odd" when f (-x) = - f (x) for all x. ... For example, functions like
- f (x) = x3,
- f (x) = x5,
- f (x) = x7, ... are odd functions.
Answer:
x = 20
y = 10
m∡8 = 110°
Step-by-step explanation:
m∡1 + m∡2 = 180
5x + y + 3x + y = 180
8x + 2y = 180
m∡1 = m∡8 (they are alternate-exterior angles and are congruent)
5x + y = 3x + 5y
2x = 4y
x = 2y
Substitute '2y' for 'x' in 8x + 2y = 180
8(2y) + 2y = 180
18y = 180
y = 10
x = 2(10)
x = 20
m∡8 = 3(20) + 5(10) = 110°
