What is a standard triangle?
Triangles like 30,60,90 and 45 45 90 are standard triangles are standard.
What is halve 90?
Half of 90 = 45
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 90 -45?
135
Why is the sum of the measures of the acute angles of a right triangle equal to 90 degrees?
Because the total number of degrees in all triangle is equal to 180. Right triangles consist of one right angle(90) and two equal acute angles(45, 45).
What are the differences of isosceles right triangles and 30-60-90 right triangles?
isosceles are 45-45-90
What are some types of triangles by degrees?
special triangles: 45-45-90 triangle and 30-60-90 triangle
Special right triangles?
30-60-90 45-45-90
What is a standard triangle?
Triangles like 30,60,90 and 45 45 90 are standard triangles are standard.
What triangle has angles that measures 45 an 45 and 90 degrees?
Right triangles.
What triangles are classified by their angles?
Acute triangles have all of their angles less than 90 degrees. Right triangles have one of their angles equal to 90 degrees. Obtuse triangles have one of their angles greater than 90 degrees. Also, the 45-45-90 triangle and 30-60-90 triangle are useful when trying to get exact answers in trigonometry.
Why is it possible to make an issocles triangle from to right angled triangles?
Because 1 angle will measure 90 degrees and the other 2 angles will each measure 45 degrees
How many unique triangles can be made when one angle measures 90 and deg and another angle is half that measure?
The triangle will then have 3 angles of 45, 45 and 90 degrees and take the shape of an isosceles right angle triangle.
Why are 30-60-90 or 45-45-90 right triangles not helpful on quadrantal angles?
30-60-90 and 45-45-90 triangles are not particularly useful for quadrantal angles because these angles (0°, 90°, 180°, and 270°) correspond to specific points on the unit circle where the sine or cosine values are straightforward (0, 1, -1). These points do not require the detailed relationships defined by the special triangles, as the values can be directly derived from the coordinates of the circle. Therefore, the unique properties of 30-60-90 and 45-45-90 triangles are unnecessary for determining the trigonometric values at these specific angles.
When a square is divided by a diagonal it forms what kind of trangle?
It forms 2 45-45-90 triangles.
How many unique triangles can be made when one angle measures 90 and another is half that measure?
It will be in the form of an isosceles right angle triangle when it has a 90 and two 45 degree angles
Are all 45 45 90 triangles are similar to each other?
Yes or they could be congruent to each other.
