For an equilateral triangle where the width of each side is given as w and each angle is 60 degrees:r = SquareRoot(w^2 - 0.25w^2)For an isosceles triangle with two angles a and a side between them of length b.r = 0.5 * b * tan(0.5 * a)
An isosceles triangle is a triangle with 2 congruent sides and 2 congruent angles.
An isosceles triangle is a triangle with 2 congruent sides. (2 sides are the same length)
What about them? It depends on the shape! All 2 dimentional shapes are made of triangles. A triangle has a total of 180 degrees inside. A square is simply 2 triangle side by side therefore totaling 360 degrees inside. (180+180). Penticon 3 triangles hence 540 degrees. This will continue for every side added to a shape then add 180 degrees. This will look good on your maths exam (Formilure (No of sides -2)x180=total degrees)
that question can not be answered without knowing what the inside angle of the 2 equal sides is.
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.
It will be a right angle triangle with 3 inside angles that add up to 180 degrees.
Isosceles Triangle Thats 17 letters...unless you count the space as a letter. But that is the logical answer.
A right triangle had 2 perp.sides. Perp. lines meet to form right angles. i need the answer in a four letter word. :)
For an equilateral triangle where the width of each side is given as w and each angle is 60 degrees:r = SquareRoot(w^2 - 0.25w^2)For an isosceles triangle with two angles a and a side between them of length b.r = 0.5 * b * tan(0.5 * a)
The area of ANY triangle can be found using the formula: Area = Base of triangle * (1/2) * Height of triangle The height of a triangle is measured from the "bottom", or base of the triangle straight up to the top "corner". This measurement is inside the triangle. For example: An equilateral triangle has all 3 sides the same. (See the word equal?) Using your numbers, plug them into the formula and figure out what the area of your triangle is.
Possibly an equilateral triangle
An isosceles triangle has 2 equal sides and 2 equal angles.
An isosceles triangle is a triangle with 2 congruent sides and 2 congruent angles.
it took me forever to do so dont get frusterated u draw 2/3 of the outside triangle the do the inside triangle upside down then fin the outside one
To create three different drawings showing a number of circles and triangles in which the ratio is 2:3 you can: Start with an equilateral triangle, draw a circle inside it, draw an equilateral triangle inside the circle, draw a circle in the triangle and then draw an equilateral tiangle in the smallest circle. Or, you could draw 3 triangles and 2 circles in a line. Or, you could draw 3 triangles on a line with 2 circles between them.
