Understanding Perimeter and Area of Triangles
The area of a triangle is always calculated using the formula 1/2 × base × height, regardless of whether it is a right, scalene, isosceles, or equilateral triangle. Perimeter and area have practical applications, such as determining the...

Calculating the Area of a Triangle
To determine the area of a triangle, you use the formula: Area = 1/2 × Base × Height. This formula works because a triangle is essentially half of a rectangle or square. By identifying the base (the bottom side) and the height (the...

Finding the Perimeter of a Triangle: Simple Steps and Applications
To determine the perimeter of a triangle, you simply add the lengths of its three sides. Whether it’s a scalene triangle with different side lengths, an isosceles triangle with two equal sides, or an equilateral triangle where all sides...

Classifying Triangles by Their Angles: Acute, Right, and Obtuse
Triangles can also be classified based on their angles. An acute triangle has all three angles less than 90 degrees, a right triangle has one angle exactly 90 degrees, and an obtuse triangle has one angle greater than 90 degrees. No...

Understanding Triangles: Types, Properties, and History
Triangles have unique properties that define their shape, sides, and angles. They can be categorized based on their sides: scalene (all sides different), isosceles (two sides equal), and equilateral (all sides equal). Throughout history,...

Area Of A Triangle 1/2absinC
The area of a triangle is ½ the base X perpendicular height. If we don’t have the perpendicular height, there is another formula we can use: 1/2absinC which we look at in this video. We need two sides and the angle in between. This will...
