It would be an acute triangle. Basically, the one you think of when you think triangle.
A shape that has three sides and includes right angles is a right triangle. In a right triangle, one of the angles is exactly 90 degrees, and the other two angles are acute. The sides of the triangle consist of the two legs that form the right angle and the hypotenuse opposite the right angle.
A triangle has three sides and three angles.
a rhombus, a quadrilateral without right angle, a quadrilateral with equal opposite parallel sides but no right angles
To draw a heptagon with three right angles, first create a shape with seven sides, ensuring that three of the internal angles are 90 degrees. Start by drawing a right angle, then extend two lines to create the next two right angles, forming an "L" shape. From there, connect the endpoints with lines to complete the heptagon, adjusting the lengths of the remaining sides to ensure all angles add up to 900 degrees. The final shape will have the required three right angles among its seven sides.
A shape with seven sides and seven angles is called a heptagon. If it has three right angles, the other four angles must sum to a total of 360 degrees (since the total interior angle sum of a heptagon is 900 degrees). This means that the remaining angles can vary, but they must be arranged in such a way to maintain the heptagon's properties while accommodating the three right angles.
False - and false ! Not ALL angles are right-angles - and a triangle has THREE sides !
The following shape has three sides and the only angles are right angles. ----- | |___
A shape that has three sides and includes right angles is a right triangle. In a right triangle, one of the angles is exactly 90 degrees, and the other two angles are acute. The sides of the triangle consist of the two legs that form the right angle and the hypotenuse opposite the right angle.
ALL triangles have three sides and three angles. The three angles always add up to 180 degrees. A right angled triangle has one 90 degree right angle and two smaller angles. No triangle can have any parallel sides. An equilateral triangle has three equal sides and therefore three equal 60 degree angles.
No REGULAR polygon can have three right angles in it. Any polygon with five or more sides CAN have three right angles, as long as it's not regular.
If it had two right angles it would have more then three sides
hexagon
A triangle has three sides and three angles.
a rhombus, a quadrilateral without right angle, a quadrilateral with equal opposite parallel sides but no right angles
Such a three sided triangle with two right angles is impossible.
89 well all triangles have three sides so there are three angles
An equalateral triangle
