Any rectangle that isn't a square.
rectangle
This is a special case of a quadrilateral called a rectangle.
a rectangle (that is NOT a square) has 4 right angles and consecutive sides of unequal lengths.
a circle
An acute triangle.
A right triangle and an isosceles triangle are alike in that both are specific types of triangles defined by their angles and side lengths. A right triangle has one angle measuring 90 degrees, while an isosceles triangle has at least two sides of equal length, which can create various angles including right angles. Both types of triangles can be used in various geometric applications and share properties related to the sum of their angles, which always equals 180 degrees. Additionally, both can be classified further based on their side lengths and angles.
All triangles that are not right triangles.
right
A geometric figure with three line segments as sides is called a triangle. Triangles can be classified based on their angles (acute, right, or obtuse) or their side lengths (scalene, isosceles, or equilateral). Each triangle has three vertices and the sum of its interior angles always equals 180 degrees.
