It is possible to construct an isosceles triangle of given dimensions using just a compass and straightedge. See these three constructions: Isosceles triangle, given base and side. Isosceles triangle, given base and altitude.

An equilateral triangle is one with three equal sides. An isosceles triangle is one with two equal sides. Therefore, every equilateral triangle is isosceles, but not every isosceles triangle is equilateral.

In any isosceles trapezoid, two opposite sides (the bases) are parallel, and the two other sides (the legs) are of equal length (properties shared with the parallelogram). The diagonals are also of equal length.

Isosceles Right Triangle. is called Pythagoras's constant.

We are talking about right triangles with equal in length two catheti. One angle, across the hypotenuse, is 90o . Two others must be equal since a triangle is isosceles, that is they are equal to 45o each. So, any right isosceles triangle has angles 90o , 45o and 45o .

Therefore, an isosceles triangle and a scalene triangle can never be similar. SOLUTION: Always; sample answer: Equilateral triangles always have three 60° angles, so the angles of one equilateral triangle are always congruent to the angles of a second equilateral triangle.

A three-sided polygon is a triangle. There are several different types of triangle (see diagram), including: Equilateral – all the sides are equal lengths, and all the internal angles are 60°.

The number of triangles is 1, 8, 35, 110, 287, 632, 1302, 2400, 4257, 6956 for polygons with 3 through 12 sides. If we connect all vertices of a regular N-sided polygon we obtain a figure with = N (N - 1) / 2 lines. For N=8, the figure is: Careful counting shows that there are 632 triangles in this eight sided figure.

Triangles are shapes with three sides. There are different names for the types of triangles. A triangle's type depends on the length of its sides and the size of its angles (corners). There are three types of triangle based on the length of the sides: equilateral, isosceles, and scalene.

Answer and Explanation: No, all isosceles triangles are not similar. An isosceles triangle is a triangle with two sides of equal length.
