Isosceles Triangle -- from Wolfram MathWorld
Isosceles Triangle. An isosceles triangle is a triangle with (at least) two equal sides. In the figure above, the two equal sides have length and the remaining side has length .This property is equivalent to two angles of the triangle being equal.
Isosceles triangle - Wikipedia
In geometry, an isosceles triangle is a triangle that has two sides of equal length. Sometimes it is specified as having exactly two sides of equal length, and sometimes as having at least two sides of equal length, the latter version thus including the equilateral triangle as a special case.Examples of isosceles triangles include the isosceles right triangle, the golden triangle, and the ...
Triangle - Wikipedia
By lengths of sides. Triangles can be classified according to the lengths of their sides: An equilateral triangle has all sides the same length. An equilateral triangle is also a regular polygon with all angles measuring 60°.; An isosceles triangle has two sides of equal length. An isosceles triangle also has two angles of the same measure, namely the angles opposite to the two sides of the ...

Isosceles Triangle Unit
Notes: 1) After independently coming up with this unit I discovered that Jeannine Mosely came up with it as well. 2) The finished unit in step 5 can be used for constructing both the lesser and the greater stellated dodecahedra.
Types of Triangles
Types of Triangles Right triangle: Has one 90 degree angle Equilateral triangle: All angles are the same (60 degrees) Isosceles triangle: Has two angles the same and two sides the same Scalene triangle: Has all three angles and all three sides different Obtuse triangle: Has one obtuse angle, greater than 90 degrees The sum of all angles in a triangle is _____ degrees.
2 Simple Ways to Find the Area of an Isosceles Triangle ...
Find the isosceles triangle's base. Now you have the formula, but what exactly do "base" and "height" mean in an isosceles triangle? The base is the easy part: just use the third, unequal side of the isosceles.
Isosceles Triangle Quilt Along- Making the Quilt
Step 1: Cutting your fabric. You will need to cut your fabric into strips that are 6" x WOF (width of fabric) so if you are using fat quarters you will have 3 strips that are 6"x22", if you are using half yards you will have 3 strips that are 6"x44", etc.
Triangles - Equilateral, Isosceles and Scalene
Equilateral, Isosceles and Scalene. There are three special names given to triangles that tell how many sides (or angles) are equal. There can be 3, 2 or no equal sides/angles:
