obtuse angle 90-180. It is more than 90° and less than 180°. The smaller angle is an Obtuse Angle, but the larger angle is a Reflex Angle.
reflex angle 180-360A reflex angle is an angle that measures greater than 180 degrees and less than 360 degrees. Find its measure by first determining the measure of the corresponding acute or obtuse angle. Then subtract from 360 to find the difference. The difference is the measure of the reflex angle
we have covered measuring angles and naming angles and types of angles we also covered there degrees of each one

perimeter and area
the perimeter is the length of the outline of a shape. To find the perimeter of a rectangle or square you have to add the lengths of all the four sides. x is in this case the length of the rectangle while y is the width of the rectangle. The area is measurement of the surface of a shape.
Area is the quantity that expresses the extent of a two-dimensional figure or shape, or planar lamina, in the plane. Surface area is its analog on the two-dimensional surface of a three-dimensional object.
we also learnt how to find the area and per minter to find the area you times for triangles you do base ,height and then divide it by 2 for other shapes it is l +w+h for perimeter you add the outside numbers
