Isosceles Triangle -- from Wolfram MathWorld
An isosceles triangle is a triangle with (at least) two equal sides. In the figure above, the two equal sides have length b and the remaining side has length a. This property is equivalent to two angles of the triangle being equal. An isosceles triangle therefore has both two equal sides and two equal angles. The name derives from the Greek iso (same) and skelos (leg).
Isosceles triangle - Wikipedia
In geometry, an isosceles triangle is a triangle that has two sides of equal length. Sometimes it is specified as having two and only 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.. By the isosceles triangle theorem, the two angles opposite the equal sides are themselves equal ...

Try this Drag the orange dots on each vertex to reshape the triangle. Notice it always remains an isosceles triangle, the sides AB and AC always remain equal in length
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.
a 45 a Isosceles triangle
The northward and westward motions can be considered separately. In this case they are each described by constant velocity motion.
Scalene triangle - math word definition - Math Open Reference
To see why this is so, imagine two angles are the same. The triangle would then be an Isosceles triangle, which has two sides the same length.
