What are the only two triangle congruence shortcuts that do not work?
Cristycakes
The only Two Triangle congruence shortcuts that do not prove congruence are:
1.AAA( Three pairs of angles in a triangle) & 2.ASS or SSA(If the angle is not in between the two sides like ASA.

How do work out the area of a right angled triangle?
A right triangle is easy, simply multiply the two sides and divide by two
How do you work out the perimeter for a triangle?
-- Make sure you have the lengths of all three sides -- Add up the lengths of all three sides to get the perimeter of the triangle.
How do you work out the area of a triangle inside a square?
If you want to figure out just the area of the triangle, the formula is base times height divided by 2. It does not matter if it is inside a square, as long as you have the legnths of all they sides you need to calculate the area of that triangle. If you do not, It would be very difficult.
Does An exterior angle of a triangle equals 180 minus the adjacent interior angle?
Yes it does. Good work!
You know base and angles how do I find height of isosceles triangle?
Use the sine rule to work out one of the sides. (a/sina = b/sinb = c/sinc) Then as it is an isosceles triangle the perpendicular dropped from the apex will (a) bisect the base and (b) form a right angle with the base. Now you know one side and the hypotenuse of a right-angled triangle and you use Pythagoras (a2 + b2 = c2) to solve the 'other' side of that, which is the height of the isosceles triangle.
How do you work without a mouse in Linux?
use shortcuts. you can work on the computers without mouse and cursor using those shortcuts.
How do you work out the angles of a triangle with only one angle?
You cannot.
Does a hot tub help lose body fat?
No. Eating less, exercising more are the ONLY things that will lose weight. There ARE no shortcuts that work.
Why is goal congruence important to an organization?

How do you work out the isosceles triangle when they only give you the exterior size of 92?
State the question better.
How does a triangle sequence work?
A triangle that is in a sequence
How do you work out the lengths of each side of an equilateral triangle?
Use a ruler and measure one side only. All sides will measure the same if the triangle is equilateral.
Will the cheat engine be illegal on Poptropica?
Cheat engines only work for programs that run on your computer or game system. Poptropica runs on the company's servers and cheats, hacks, and shortcuts do not function.
When does the pythagoream therom not work?
When a triangle is not a right triangle
The dose the Pythagorean Theorem only work on right triangles?
I quote " The square on the hypotenuse of a rightangled triangle..."
How do you work out the angles in a triangle with only 3 sides and no angles?
use the inverse sine or cosine or tangent
How do you find the area of a triangle given only the perimeter?
It is possible depending on what type of triangle it is. For instance if it was an equilateral triangle then all sides would be equal and then by means of Pythagoras' theorem you could work out the height of the triangle and using the formula: 1/2*base*height = area
