Answer. Finding the missing side of a right triangle is a pretty simple matter if two sides are known. One of the more famous mathematical formulas is a2+b2=c2 a 2 + b 2 = c 2 , which is known as the Pythagorean Theorem.

Your final answer is √32 miles.

The length of the unknown leg in the right triangle is 3 units.

The Pythagorean theorem states that a2 + b2 = c2 in a right triangle where c is the longest side. You can use this equation to figure out the length of one side if you have the lengths of the other two. The figure shows two right triangles that are each missing one side’s measure.

hypotenuse

The sides of a right triangle have different names: The longest side, opposite the right angle, is called the hypotenuse. In the diagram, the hypotenuse is labeled c. The other two sides are called the legs of the triangle.

In geometry, a hypotenuse is the longest side of a right-angled triangle, the side opposite the right angle.

Every triangle has three sides and three angles, some of which may be the same. The sides of a triangle are given special names in the case of a right triangle, with the side opposite the right angle being termed the hypotenuse and the other two sides being known as the legs.

In geometry, an isosceles triangle is a triangle that has two sides of equal length. Sometimes it is specified as having exactly two sides of equal length, and sometimes as having at least two sides of equal length, the latter version thus including the equilateral triangle as a special case.

To learn about and construct the seven types of triangles that exist in the world: equilateral, right isosceles, obtuse isosceles, acute isosceles, right scalene, obtuse scalene, and acute scalene.

An isosceles triangle can be drawn in many different ways. It can be drawn to have two equal sides and two equal angles or with two acute angles and one obtuse angle.

One of the most famous is the “3, 4, 5 triangle.” The third side–the side opposite the right angle–is called the hypotenuse of the right triangle. The two shorter sides are usually called “legs.” This formula is called the Pythagorean Theorem in honor of Pythagoras.

The six types of triangles are: isosceles, equilateral, scalene, obtuse, acute, and right.

• An isosceles triangle is a triangle with two congruent sides and one unique side and angle.
• An equilateral triangle is a triangle with three congruent sides and three congruent angles.

A polygon with three sides is a triangle. We name a triangle by its three vertices. Notice the use of the little triangle next to the vertices to indicate we are referring to the triangle instead of the angle. A polygon with four sides is a quadrilateral.

A quadrilateral is a four-sided two-dimensional shape. The following 2D shapes are all quadrilaterals: square, rectangle, rhombus, trapezium, parallelogram and kite.

Myriagon

A regular tetradecagon has Schläfli symbol {14} and can be constructed as a quasiregular truncated heptagon, t{7}, which alternates two types of edges. The area of a regular tetradecagon of side length a is given by.

enneagon

dihectogon

In geometry, a hexagon can be defined as a polygon with six sides. The two-dimensional shape has 6 sides, 6 vertices and 6 angles.

heptagon

regular triacontagon

An 18-sided polygon, sometimes also called an octakaidecagon.
