What else can I help you with?
You have 5 sides all your angles are less than 180?
pentagon
Kinds of angles according to sides?
Greater than zero, less than 90 - Acute Equal to 90 - Right Greater than 90, less than 180 - Obtuse Equal to 180 - Straight Greater than 180, less than 360 - Reflex (all measures are in degrees).
Which shape has an obtuse angle?
An obtuse angle is greater than 90 but less than 180 degrees
What shape has 2 right angles 2 acute angle?
No shape does. If a shape has four angles, the sum of the four angles is 360°. If two are right angles, their sum is 2 x 90° = 180°, leaving 360° - 180° = 180° for the two remaining angles. An acute angle is less than 90°, so the sum of two acute angles is less than 90° + 90° = 180°, but in this shape their sum must be equal to 180°; thus no shape can exist. If one angle is acute and the other is obtuse, then their sum can be 180° and the shape is a trapezium.
What is the number of sides when the interior angle is 180 degrees?
A shape has three sides if its interior angles add up to equal 180 degrees.
