What is that triangle instrument called?
It is called a "triangle" I know, not very imaginative is it?
How do you find which triangle if you know the lengths of the sides of a triangle whether it is isosceles or equilateral or scalene?
You look at the lengths of the sided of the triangle. If the two lengths are same, the triangle is an isosceles triangle. If all the lengths are same, the triangle is an equilateral triangle. If none of the lengths are same, the triangle is a scalene triangle.
How do you find the length of a side in a triangle that is not a right triangle?
Use either the Sine or Cosine rules depending on the information you know about the triangle.
How do you know the measure of each angle in an equilateral triangle using what you know about equilateral triangles and the degree measure of a circle or a straight angle?
the sum of the angles of a plane triangle is always 180° In an equilateral triangle, each of the angles is = Therefore, the angles of an equilateral triangle are 60°
Can you think of another combination of triangle classification that is impossible?
an Obtuse Equilateral triangle is one.... sadly i don't know any other :(
A triangle that has angles that measures 454590 degree is a?
A 45-45-90degree triangle is classified as an isosceles triangle.
Is right triangles with 2 congruent legs is always a 454590 triangle?
Yes if you mean in degrees
How do you know if a triangle is a right triangle?
If it has one 90 degree angle then it is a right triangle.
How do you know when a triangle is 90 degrees?
we know that a triangle is 90 degrees by measuring its length or it can be known as right triangle which measures 90 degrees.
How can you use what you know about special triangle to find the perimeter?
The answer depends on what is special about the triangle and what else you know about it.
How do you know when a triangle is scalene?
You know a when a triangle is scalene if all its sides are diffrent lenths none of them are the same
How do you know a triangle is isosceles?
You know when a triangle is isosceles because two of it's sides are corresponding (the same).
What is that triangle instrument called?
It is called a "triangle" I know, not very imaginative is it?
A triangle with one right angle?
A triangle with 1 right angle is a right angle triangle.
How do you know if a triangle is a right triangle by it's sides?
C2=a2+b2
If you know that triangle RST is congruent to triangle ABC what else do you know to be true?
That all sides and angles are also equal.
What shape has three sides that are not equal but have a right angle?
with the three sides you know it will be a triangle, it is a right triangle, it is not an equilateral triangle or an isosceles triangle... so it must be a right scalene triangle
