No you cannot make a triangle with two right angles. In all triangles the sum of the angles is always 180°. Also all triangles have three angles. If there are two right angles, you already have 180° and cannot have another angle to complete the triangle.

Why is not possible to make an equilateral triangle on a geoboard?
because it has angles so you can't make a triangle
Different types of triangles can be created by combining 2 what terms scalene isosceles equilateral acute obtuse and right. What combination of these terms will not form triangles?
An equilateral triangle has to be acute. All the sides are the same size, and all the angles are the same size. You can't have three 90 degree angles in a triangle or three angles that are more than 90 degrees in a triangle. Therefore the angles have to be acute. An isosceles triangle will have two angles at are the same size. You can't have two 90 degree angles or two angles over 90 degrees in a triangle, but the triangle only has to have one of those angles to be either right or obtuse. The right or obtuse angle must be between the two sides that are equal and the two angles that are equal have to be acute. So then an isosceles triangle can be any of the three - acute, obtuse, or right. A scalene triangle has three unequal sides. Therefore, the angles will all be unequal. Can you think of any three angles that are all less than 90 degrees that will add up to 180 degrees? (acute?) What about any two angles (not equal) that will add to another 90 degree angle to make 180 degrees? (right?) What about any two angles (not equal) that will add to another angle larger than 90 degree to make 180 degrees? (obtuse?) Therefore there are 7 possible combinations.
How do you make an angle without using compass and protractor?
By drawing regular polygons as for instance a square will have 4 equal right angles and an equilateral triangle will have 3 equal 60 degree angles.
Does the angles 40 degrees 60 degrees and 80 degrees make a triangle?
Yes because there are 3 interior angles in a triangle that add up to 180 degrees
Which triangle is the only triangle that has perpendicular lines?
The Right Triangle. Perpendicular lines make a right angle.
Can you make a triangle with 2 right angles?
no
Why is not possible to make an equilateral triangle on a geoboard?
because it has angles so you can't make a triangle
What is the name of a triangle that has two right angles?
It is impossible to have a triangle with two right angles. This is because a triangle=180 degrees. Two right angles would make up all of the 180 degrees.
What do you call a triangle with two obtuse sides?
In normal geometry, it's not possible to make a triangle with two obtuse angles. It is possible to make a triangle with two obtuse angles in spherical geometry -- it's a kind of "spherical triangle". It is possible to make a triangle with two obtuse angles in some kinds of non-Euclidean geometry -- it's a kind of "non-Euclidean triangle".
Can a right triangle have two angles that measure 38degrees an 54 degrees?
No. A triangle has 180 degrees in it. A right triangle has an angle of 90 degrees. That leaves the other two angles to total 90 as well. 38+54=92 which would make the triangle equal 182 degrees. this is not possible.
What is a triangle with no right angles?
Equilateral Triangles do not contain right angles, since all angles in this shape are equal and it is impossible to make a triangle that consists of three 90 degress angles. Isosceles and Scalene may contain a right angle.
How do you make a triangle with 3 right angles?
A triangle cannot have more than one right angle, which measures 90o. The sum of all three angles in a triangle must equal 180o.
A triangle with two acute can be called a right angle?
Right triangles have two acute angles, but that doesn't make them right. Having a right angle makes them right.
How do you make a triangle with 2 right angles?
A triangle can not contain two right angles. This is because:A triangle contains three separate anglesThe sum of the angles in a triangle is equal to 180 degreesA right angle is 90 degreesBecause 90 + 90 = 180, that leaves the remaining angle in the triangle at 0 degrees, making the shape not a triangle but a line segment.
How many right angles do you need to make an right triangle?
Just one of them and two acute angles that add up to 90 degrees.
Make a right angled isosceles triangle This is a triangle with a right angle and two equal anles that are not right angles What is the size of these non right angles?
45 degrees. they have to be the same angle, because they are opposite equal lengths, and when added together they must equal 90, so as to make the total of the angles 180.
What conclusion can you make about the angle in a right triangle?
Since the sum of the measures of the angles in a triangle is 180°, and a right angle has a measure of 90°, it follows that the other two angles together have a measure of 90°.
