Since 2 of it's angles are equal (45 degrees), you have an isoceles triangle. Hence, two of its sides are the same.
Since the other angle is 90, you have a right angle triangle. This means that if you're missing the hypotenuse, you can use the Pythagorean theorem to find it.
H^2 = A^2 + B^2
Where H is the length of the hypotenuse, and A and B are the lengths of the other 2 sides. (Here, A = B).

How do you find the sides of a right angled isosceles triangle when you know the angles?
You cannot. A right angled isosceles triangle will always be 90-45-45 so knowing the angles does not add any information. Without knowledge of any one side, you cannot distinguish between the infinitely many similar 90-45-45 triangles.
What is a rule for the 45-45-90 right triangle?
There is no single rule. It is a right angled isosceles triangle. Its long side (hypotenuse) is sqrt(2) times the short sides.
Carey drew an equilateral triangle with a perimeter of 45 inches. He dilated the triangle by a scale factor of 0.6. What is the length of each side of the image of the dilated triangle?
Ok if the triangle is equilateral then all the sides have to have the same length. Since the perimeter is 45 inches that means each side is 15 inches. 45 / 3 = 15 Now if he dilates the triangle by a scale factor of 0.6 we have to multiply the length of each side by 0.6. 15 * 0.6 = 9 So the answer is 9 inches
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.
Explain why the tangent of 45 equals 1?
Tangent is determined by the ratio of the side opposite the angle over the one adjacent to it. In a 45-45-90 triangle, the ratio of these sides is 1. This is because the side opposite one of the 45 degree angles is adjacent to the other, and vise versa.
How you find the height of triangle if you have the perimeter?
For example, if you have a 45-45-90 triangle. Let's say to sides are 14 and the base is 28. The perimeter would be 56. Divide the base by 2 to get 14. Then use the pythagorean theorem to find the missing side. c= 14, a= 14. and b= ?
How do you find the perimeter of a triangle with only one side being 45 inches?
if the triangle was an equilateral triangle, you would have been able to just multiply 45 with 3... but if the triangle was some other kind of triangle, you would have to know the other sides
What is in a right triangle the side that include the right angle in an isosceles triangle the pair of congruent side?
The angles will be 90, 45 and 45 degrees
How do you find a missing dimension for a right angle triangle?
In a right triangle, all the angle measurements together add up to be 180 degrees. And since it is a right triangle, one of the three angles is 90 degrees so if you are given one of the angles other than the right angle's measurements, you can find the angle measurements. Here's an example: There is a right triangle. One angle measures to be 45 degrees. What is the missing angle measure? Well we know that one angle must be 90 degrees and the other (as we were told) is 45 degrees. 90+45=135 and we know that a right triangle=180 degrees total and 180-135= 45. The missing angle is equal to 45 degrees! hope this makes sense and it helped.
A triangle with sides of lengths 27 36 and 45 is a right triangle?
yes it is.. with 45 being the longest side..:)
What is the unknown side of the right triangle?
It has to be 45 degrees.
If the side opposite a 45 degree angle in a right triangle is 12.5 meters how long is the side adjacent to the angle?
It's also 12.5 meters. The two sides of the triangle are the same length, because it is an isosceles right triangle(90-45-45).
Which of these side lengths makes the triangle obtuse?
15,36 answer: 45
What has 3 sides 1 square corner and 2 side the same length?
isosceles right triangle or the 45 45 right triangle
If one acute angle on a right triangle is forty five degrees what is the measure of the other acute angle in the triangle?
since it is a right triangle there is one 90 degree angle and another of the angles is 45 degrees. there is 180 degrees in a triangle so the missing angle is 45 degrees.
How do you find the hypotenuse of 45 45 90 right triangle?
Using Pythagoras' theorem
If two sides of a triangle equal 45 what does the third equal and what kind of triangle is this?
If two sides of a triangle each have length of 45 units, then the triangle is isosceles,and the third side can have any length less than 90 units.
