Equilateral Triangles
Hi Welcome to MooMooMath.
Today we are going to look at Equilateral
Triangles.
Up here I have two different triangles.
The first one we know is equilateral because
all three sides are marked congruent.
You might see a congruent symbol like that
(points to triangle) or you might see that
the measure of each side is equal.
So there is two ways to show that the different
sides are equal.
On the second one let's look at it in perspective
of the actual measure of the angles.
We know that a triangle adds up to 180 degrees.
So if we have three equal angles we are going
to take that and divide it by three.
So 180 divided by three is equal to 60.
That means each of these angles have to measure
60 degrees.
If the three angles measure 60 then it is
an equilateral triangle.
So let's look at the rules.
The first rule is that all three sides of
the triangle are congruent which just means
they are equal, and all three angles have
to be congruent, which are equal measures.
In an equilateral triangle since you have
triangle and it always adds to 180 the measure
of the angles will always be 60.
Hope this video was helpful.
