a tiangle with a angle over 90 degrees
3 sides because every tiangle has 3 sides.
A triangle is called a scalene triangle if its sides have different length measures. Since in an isosceles triangle there are two congruent sides, it cannot be a scalene triangle.
Well, the sum of a triangle is always 180 degrees. If it is a right tiangle, then you know that one angle is 90 degrees and you have to fiure out the other two.
Pascal's tiangle first appear in the year 1653.
There are 5 which are:- Scalene triangle Obtuse triangle Right angle triangle Isosceles triangle Equilateral tiangle They all have 3 sides and their 3 interior angles add up to 180 degrees
Heron's formula to find area of triangle semi perimeter(s)=sum of all the sides of triangle/2 area of tiangle=P[s(s-first side)(s-second side)(s-third side)]1/2

The formula is: Area = base * height. With an isosceles triangle, two of the angles are congruent and their opposite sides are congruent. There is one remaining angle (that will be referred to as the top angle) and its opposite side (the base). You will probably have to drop a perpendicular line from the top angle to the base. This will bisect the base into two equal parts. Also, you now have two congruent right triangles. It depends on what you know with this triangle in order to find its height and/or base. However, use the Pythagorean Theorem and I'm sure you can work it out.
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.
