An equilateral triangle is also a regular polygon with all angles measuring 60°. In an isosceles triangle, two sides are equal in length. (Traditionally, only two sides equal, but sometimes at least two.) An isosceles triangle also has two angles of the same measure; namely, the angles opposite to the two sides of the same length. Oct 06, 2018 · Basic: area of a triangle with base and height lengths. Anyhow, area of a triangle with known base and height is \$ A = {b×h}/2\$. b is base. h is height. The \$1/2\$ (divided by two or multiplied by half) is based on a diagonally and evenly cut rectangle or square, from one corner to the the other diagonally opposite corner into two pieces.

Sep 13, 2008 · Construct an equilateral triangle. Explain in great detail your technique in creating the equilateral triangle. (state the steps carefully and in chronological order.) the reader should be able to follow the steps and create their own equilateral triangle using Geometer's Sketchpad. 5). State your conjecture about the medians of a triangle. 6).
Every triangle has three medians, and they all intersect each other at the triangle's centroid. The centroid divides each median into parts in the ratio 2:1, with the centroid being twice as close to the midpoint of a side as it is to the opposite vertex. We use Apollonius's theorem to calculate the length of a median from the lengths of its side.

The name hypotenuse is given to the longest edge in a right-angled triangle. (It is the edge opposite to the right angle and is c in this case.) Where (for brevity) it says 'edge a', 'angle B' and so on, it should, more correctly, be something like 'length of edge a' or 'edge-length' or 'size of angle B' etc.
