Because a triangle can only have 3 angles.
It is a triangle.
Although a triangle must have at least two acute interior angles, a square has four interior right angles and no acute angles. And as regular polygons have increasing numbers of sides, their interior angles get larger.
If the figure has only four sides all together, then it's not possible for all four angles to be acute.
no triangle do not have four congruent angles
The main differences are. A triangle is three sided while a rectangle is four sided. The corners of a triangle can be any angle. All corners of a rectangle must be 90 degrees. This means that the left and right sides are parallel, and the top and bottom sides are parallel.
A rhombus will either have four right angles, or two acute angles and two obtuse angles.
No, It is not possible to have a quadrilatera with four acute angles because the addition of four angles for quadrilateral = 360 & acute angle is less than 90 degree
Parallelogram
There are right angles, acute angles, obtuse angles, and straight angles.
A rhombus is a shape having two acute angles and four equal sides.
The four angles are acute, obtuse, right, and Strait!Thank you!-Chloe Sciuto
