Are all scalene triangles acute triangles?
No, scalene triangles can be obtuse, right or acute triangles. A 3 - 4 -5 right triangle (lengths of the sides) is one example of a right-scalene triangle. In fact, with the exception of the [45°, 45°, 90°] right triangle (which is isosceles) all other right triangles are scalene.
Are all triangles equilateral?
No.Equilateral triangles must have equal angles (all 60 degrees) and equal length sides; there are also:Isosceles triangles which have two equal angles and two equal sides;Scalene triangles which have all three sides, and hence all three angles, of different lengths;Right angled triangles (which can have all sides of different lengths, or two sides of equal length) have (as the name suggests) one right angle. This means Pythagoras and the trigonometric ratios can be used on its side lengths.
How can you tell by a triangle's side lengths if it is a right triangle?
If the tree sides of the triangles form a Pythagoras triplet then we can say that the angle opposite to the greatest side is a right angle.
What are the side lengths of a triangle with an area of 6?
If its a right angle triangle then its side lengths could be 3, 4 and 5
Are scalene triangles all obtuse?
No, a scalene triangle is simply a triangle where all angles are not equal and all side lengths are not equal, therefore they can or cannot be obtuse.
Do right triangles and hexagons both have all sides of equal lengths?
Only when they are equilateral triangles and regular hexagons that both will have sides of equal lengths.
Why Does pythagorean theorem don't work for non right angle triangles?
The Pythagorean theorem specifically applies to right-angled triangles because it is based on the unique relationship between the lengths of the sides in such triangles. It states that the square of the length of the hypotenuse equals the sum of the squares of the other two sides (a² + b² = c²). In non-right triangles, this relationship does not hold, as the angles and side lengths do not conform to the theorem's criteria. Instead, the Law of Cosines is used for non-right triangles to relate their side lengths and angles.
Are all scalene triangles acute triangles?
No, scalene triangles can be obtuse, right or acute triangles. A 3 - 4 -5 right triangle (lengths of the sides) is one example of a right-scalene triangle. In fact, with the exception of the [45°, 45°, 90°] right triangle (which is isosceles) all other right triangles are scalene.
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. :)
Are the two right triangles trs and wuv?
To determine if triangles TRS and WUV are right triangles, we need to check if they each contain a 90-degree angle. This can be done by examining the angles or using the Pythagorean theorem if the lengths of the sides are known. If both triangles have a right angle, then they are indeed right triangles. If not, at least one of them is not a right triangle.
What are the different application of trigonometry?
Trigonometry is used to find the properties of triangles and Pythagoras' theorem is used to find the lengths and angles of right angle triangles.
Are all triangles equilateral?

Could a triangle be right?
Sure. There are right triangles.
Are all right triangles congruent?
No, not all right triangles are congruent. Right triangles can have different side lengths and angles, as long as one angle is 90 degrees. Two right triangles are congruent if their corresponding sides and angles are equal, which is determined by criteria such as the Hypotenuse-Leg (HL) theorem or the Side-Angle-Side (SAS) criterion. Therefore, while some right triangles can be congruent, many others will not be.
What is a way to prove that two right triangles are congruent?
Place them on each other and they should have the same lengths and angles.
What size and shape do two congruent triangles have?
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. :)
Is a triangle with sides 60 80 and 100 a right triangle?
Yup, it follows the 3, 4, 5 rule (or in this case 6, 8, 10). Triangles with those ratios in the lengths of its sides are always right triangles
