Here is an equilatral triangle inside a rectangle how do you calculate the value of x?
the angle in a rectangle is 90 degress angles in a equilateral triangle is 60 degree each. in this question they usually give you the triangle at an angle and give you what the angle is. so if you add them together they should all add to 90 degrees. so basically the trick is in what type of triangle it is.
Can an isosceles triangle be a right angle triangle?
no an isosceles triangle can not be a right angle triangle because with an isosceles the two sides meet at a point creating a vertisce which a right angle triwngle does not have hope this helpsImproved Answer:-Yes it can providing the interior angles are 90 45 45 degrees which will give a triangle of two equal sides making it both an isosceles triangle and a right angle triangle.
How do you find a missing angle for a triangle?
Subtract the two known angles from 180 degrees will give you the missing angle
Can you give me an example of an area of an obtuse angle?
Right triangle square rectangles
Can an obtuse triangle have a right angle as one of its angles give reason?
No The reason is that an obtuse angle is over 90o so with a second angle of 90o you already have angles totalling more than 180o which is impossible in a triangle.
If they give you 16 63 65 is it a right triangle?
Yes because the dimensions given comply with Pythagoras' theorem for a right angle triangle
How do you use the measures of a triangle to show that a triangle is a right triangle?
Using a protractor which should give a measure of a 90 degree angle and two acute angles that add up to 90 degrees.
What is a triangle with two equal sides but no right angle with a picture of what?
It's a confused give way sign in London
What are some example problems of interior angle of a triangle?
The measure of the sides of the triangle is 12x +2, 13x +1 and x-15. Give the value of each side.
What is the trisect angle on an equilateral triangle?
An equilateral triangle has 3 equal angles of 60 degrees that add up to 180 degrees and trisecting a 60 degree angle equally would give 3 equal 20 degree angles.
How would you work out the perpendicular height of a triangle if they give you the area?
I think you need at least one other piece of information. A length of a side? An angle? Is it a right angled triangle?
Number of angles in a plane triangle?
I suggest you give some thought to the meaning and derivation of the word "TRI-angle" Three
