no. The sum of the angles must be 180. 90+90+90=270. Plus, If you tried to make a triangle with 3 right angles, you would end up with an incomplete rectangle

Which shapes have only acute angles?
some triangles and rhombuses. trapoziods do not have acute angles it has obtuse angles. :)
What are some special right triangles?
your mom is the right triangles
Are some right triangles also the same as equilateral triangles?
No...
When do you say that two triangles have the same shape?
well, they could be congruent, there are some rules for congruency, to be congruent two triangles have, ASA-two angles the same with a side length between them. SAS-two side lengths the same and a same angle between them. SSS-all 3 side lengths the same. RHS-if the triangles are right angles ,and the hypotenuse are the same. ;or they could be mathmatically similar. :)
Why can some isosceles triangles be ringt angle triangles?
An isosceles triangle only requires that two of its inside angles be equal to eachother. Therefore, a right angle triangle (90 degree inside angle) with two 45 degree inside angles on the the two other corners would be considered an isoceles triangle. However, this would be the ONLY right angle triangle that would be considered an isoceles triangle since all inside angles must add up to 180 (90+45+45=180).
Are triangles equilateral?
Some triangles are equilateral, but not all of them. There are three types of triangles. Triangles which have three equal sides and three equal angles are called equilateral triangles. Isosceles triangles have two equal sides and two equal angles. Scalene triangles have no equal sides and no equal angles.
Why isn't some right triangles the same as equilateral triangles?
-- All three sides of an equilateral triangle are the same length. It's impossible for the sides of a right triangle to all be the same length. -- A right triangle must have a right angle in it. All three angles of an equilateral triangle are the same size. It's impossible for all 3 angles in a triangle to all be right angles.
Shapes with no right angles?
Most shapes have no right angles. Circle, pentagon, hexagon etc. Ones that do include the square and some triangles.
Some triangles can have more than one right angle?
It can have multiple right angles and also be purely of right angles
What shape does triangles make?
Triangles can make various shapes depending on their sides and angles. Some common shapes formed by triangles include equilateral triangles (with three equal sides), isosceles triangles (with two equal sides), scalene triangles (with no equal sides), and right triangles (with one 90-degree angle).
Are some right triangles also equilateral triangles?
no because an equilateral triangle has 3 sides that have equal angles and is not 90 degrees
What are some adjectives that describe right triangles?
Well you can describe it with its shape like maybe its angles.
Does every triangle have to have an obtuse angle?
no Not every triangle has to have one. Some triangles may be acute, meaning that none of their angles are over 90. Some triangles may be right, meaning that there is one right angle. Although some triangles may be obtuse, not all triangles are obtuse.
How you can find a shape with right angle?
Any and all squares and rectangles. Every one of these two shapes has only right angles. Though some triangles also have right angles.
How many angles are in four triangles?
1 triangle = 3 angles so 4 triangles = 4 x 3 = 12 angles unless some triangles are within others
Some triangles have three acute angles?
As long as all the angles of a Triangle add up to 180, it works. So 60 and 60 and 60 word
What shapes contain right angles?
Squares, rectangles, and some triangles, most commonly. Any polygon could have a right angle if it is irregular.
