Is a triangle with two congruent angles always a 45-45-90 triangle?
No because an isosceles triangle has various two congruent angles. A 45-45-90 triangle is technically an isosceles triangle.
How many perpendicular lines does an isosceles triangle have?
If it is a 45° 45° 90° isosceles right triangle, then there are 2 sides that are perpendicular.
Why does the acute angles in an isosceles right triangle always measures 45 degrees?
The question lists three facts: "triangle", "right", and "isosceles". Each fact carries important information. -- "triangle" ... The three angles in any triangle always add up to 180 degrees -- "right" ... One angle in a right triangle must be a right angle = 90 degrees. That leaves the other 90 degrees for the other two angles to share. -- "isosceles" ... Two of the angles in an isosceles triangle are equal. If there are 90 degrees to share between them, then each of them is 45 degrees.
What is triangles measure 45 45 and 90?
These are the degrees of each angle. It is a right triangle, and it also is an isosceles triangle.
What are the angles of a right isosceles triangle?
The two other angles are 45 degrees each. The three angles of every triangle always add up to 180 degrees. -- A right triangle is a triangle that has a right angle in it. -- A right angle is 90 degrees. -- That leaves 90 degrees for the other two angles in the right triangle. -- If it happens to be isosceles, then the other two angles are equal. -- Those must both be 45 degrees.
Is an isosceles right triangle always 45-45-90 triangle?
Yes
True or false An isosceles right triangle is always a 45-45-90 triangle?
True
Is an isosceles triangle an right triangle?
Not normally but if it has angles of 90, 45 and 45 degrees it is then both a right angle and an isosceles triangle
Can an isosceles triangle Always be a right triangle?
In an isosceles triangle, two angles, and therefore sides (Base Angle Theorem), are congruent. This does not mean that all isosceles triangles are also right triangles - there is only one (45, 45, 90 triangle).
What is the 45 45 90 triangle?
It is a right angled isosceles triangle.
Can a right triangle be isosceles?
No, an isosceles triangle can not be a right triangle, because a right triangle has an angle of 90 degrees angle, and two angles of 45 degrees. An isosceles triangle has all acute angles, therefor, making it an acute triangle, so no, an isosceles triangle is not, i repeat not, a right triangle.
Can a right triangle also be a isocleles triangle?
Yes, an isosceles right triangle will have angles 45-45-90 As a side note, the ratio between the hypotenuse and the sides will always be s: s * √2 where "s" is the length of one of the sides of the isosceles right triangle.
What other triangle is similar to isosceles triangle?
A right angle triangle with 45, 45 and 90 degree angles is similar to an isosceles triangle
Is a triangle with two congruent angles always a 45-45-90 triangle?
No because an isosceles triangle has various two congruent angles. A 45-45-90 triangle is technically an isosceles triangle.
A 45-45-90 triangle is an example of an isosceles right triangle?
yes, because isosceles triangle is a triangle with two sides of equal length.
Which polygon does a 45-45-90 right triangle come from?
An isosceles right angled triangle.
What Is A True Statment About A 45-45-90 Triangle?
It is a right angle triangle or an isosceles right angle triangle
