Is equilateral triangles the same as an acute angle?
yes in fact every triangle has at least one acute angle
How many right angles in a scalene triangle?
Any triangle can have a maximum of one right angle. Most right triangles are scalene triangles. The only non-scalene right triangle is a 45° - 45° - 90° isosceles right triangle. It is not possible to have an equilateral right triangle in plane geometry. A scalene triangle does not have to have a right angle, but it can have one.
What are the names of five triangles?
Equilateral ( all sides are congruent), Isosceles (2 sides are congruent, Scalene (no sides are congruent), Acute ( three acute angles), Obtuse ( one obtuse angle), Right ( one right angle).
Does a tetrahedron have any right angles?
No. A right angle would be 90 degrees; a tetrahedron is composed of four equilateral triangles, which by definition have equal angles of 60 degrees apiece.* * * * *Wrong!A tetrahedron is a solid shape enclosed by any four triangles. Only a regular tetrahedron that requires equilateral triangles. So an ordinary tetrahedron can have right angles - up to 3 of them at one vertex.
What are the diferent types of triangles?
Equilateral - all sides and angles same; isosceles - two sides and angles same; scalene - no sides or angles same; and right-angled - one right angle.
Is a triangle with an acute angle scalene right equilateral obtuse isosceles?
It can be any one of the triangles in the list.
What triangle has at least one obtuse angle?
-- If a triangle has an obtuse angle in it, then it's called an obtuse triangle. -- No triangle can have more than one obtuse angle in it . -- Right triangles, acute triangles, and equilateral triangles don't have any obtuse angles in them.

Is there such thing as a right obtuse angle?
No. Right triangles are triangles with one angle exactly 90°, and obtuse angles are triangles with exactly one angle that is greater than, but not equal to, 90°.
What is the difference between an isosceles triangle and a right triangle?
In an isosceles triangle, two sides are of equal length. An isosceles triangle also has two congruent angles. An equilateral triangle is an isosceles triangle, but not all isosceles triangles are equilateral triangles. __________ A right triangle (or right-angled triangle, formerly called a rectangled triangle) has one 90° internal angle (a right angle). The side opposite to the right angle is the hypotenuse; it is the longest side in the right triangle. An isoceles triangle has TWO sides of equal length but and equilateral triangle has THREE sides of equal length.

In every triangle there is exactly one right angle?
Only in right angle triangles
how to make a regular hexagon out of 6 equilateral triangles?
Put one angle of each triangle at the center of the hexagon.
What is the number of sides in one equilateral triangle one right angle triangle one isoceles triangle and two scalene triangles?
1 triangle = 3 sides, no matter what kind of triangle it is 5 triangles = 3 sides each = 15 sides
