FAQs on Equilateral Triangle and its Properties Video Lecture - Class 7
| 1. What is an equilateral triangle? |  |
Ans. An equilateral triangle is a type of triangle that has all three sides of equal length. It is also known as a regular triangle.
| 2. What are the properties of an equilateral triangle? | |
Ans. The properties of an equilateral triangle include:
- All three sides are equal in length.
- All three angles are equal and measure 60 degrees.
- The altitude, perpendicular from any vertex to the opposite side, bisects the base and the corresponding angle.
| 3. How can we find the area of an equilateral triangle? | |
Ans. To find the area of an equilateral triangle, we can use the formula: Area = (side length^2 * √3) / 4. Here, the side length is the length of any one side of the equilateral triangle.
| 4. How many lines of symmetry does an equilateral triangle have? | |
Ans. An equilateral triangle has three lines of symmetry. Each line passes through a vertex and the midpoint of the opposite side.
| 5. Can an equilateral triangle have a right angle? | |
Ans. No, an equilateral triangle cannot have a right angle. Since all three angles in an equilateral triangle are equal and measure 60 degrees, there is no possibility of having a right angle (90 degrees) in an equilateral triangle.

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.
