In normal (Euclidean) geometry, no. However, there are some cases where a triangle can be drawn which does have two right angles.
Imagine drawing a great triangle on the earth between three points. The first point is on the equator in Brazil, the second point is at the north pole, and the third point is on the equator in Africa. The two angles drawn from the equator to the north pole are both 90 degrees.
This is because the surface of a sphere is not flat, but curved, and it allows the angles of triangles to add up to almost 360 degrees. We call this non-euclidean geometry.
An isosceles triangle has two equal sides and two equal angles. A right triangle is any triangle with one angle that is a right angle. A right triangle could also be an isosceles triangle, but an isosceles triangle will not always have a right angle.
It can be. If two of the sides of a right triangle are the same length then it is an isosceles triangle
A triangle with one right angle and two acute angles is called a right triangle. In a right triangle, one of the angles measures 90 degrees, making it a right angle, while the other two angles are acute, meaning they measure less than 90 degrees each. The Pythagorean theorem can be applied to solve for the lengths of the sides of a right triangle.
A right isosceles 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.
Yes
The third angle must be 90 degrees so it's a right-angled triangle
An isosceles triangle is a triangle that has two equal sides. The two angels opposite the equal sides are equal angels.
A triangle cannot have two right angles. Triangles angles should add up to 180. There are three angles. If there are 2 right angles, there would be no third angle, therefore, no triangle. XD
isosceles triangle
90 degrees
A right angle triangle can only have one right angle of 90 degrees
yes
acute, obtuse and right angles
no you dummy they have 3 :0
No. Why? Well, a right angled triangle consists of a right angle and two other angles and the total of all the angles in the triangle is always 180.180-90=90 therefore the other two angles must add up to 90 degrees.54+38=92 so a right angled triangle cannot have those two angles. Hope this helps-ish
yes
