When studying triangle properties in Grade 10 geometry, it's important to know how the angles in different types of triangles—scalene, isosceles, and equilateral—compare.
1. Scalene Triangles:
These triangles have sides that are all different lengths.
Because of this, all their angles are also different.
For example, in a scalene triangle, you might find angles measuring 60 degrees, 70 degrees, and 50 degrees.
The important thing to remember is that the sum of all angles in any triangle is always 180 degrees.
2. Isosceles Triangles:
In isosceles triangles, two sides are the same length.
This means that the angles opposite those sides are also equal.
For instance, if the angle at the top of an isosceles triangle is 40 degrees, then the two angles at the base are both 70 degrees.
When you add those angles together, you still get 180 degrees.
3. Equilateral Triangles:
Equilateral triangles are special because all three sides are the same length.
This also means that all three angles are equal, each measuring 60 degrees.
So, in an equilateral triangle, the angles are always the same.
To sum it up:
Scalene triangles have all different angles.
Isosceles and equilateral triangles have some angles that are equal.
Isosceles triangles have one pair of equal angles, while equilateral triangles have three equal angles.
Understanding these differences helps you see the beauty in the shapes of triangles!
