Divide the hypotenuse by 2 to find the short side. Multiply this answer by the square root of 3 to find the long leg. Type 3: You know the long leg (the side across from the 60-degree angle). Divide this side by the square root of 3 to find the short side.
Q. Do a triangle have parallel lines?

Q. What shapes have no parallel lines?
Explanation: The American term for such a quadrilateral is a trapezium, and the British term is a trapezoid. It is a quadrilateral that has no parallel sides.
Q. How do you know if triangles are parallel?
Determining if Two Lines are Parallel Use the Triangle Proportionality Converse. If the ratios are equal, then the lines are parallel.
Q. What do parallel lines mean on a triangle?
If a line parallel to one side of a triangle intersects the other two sides of the triangle, then the line divides these two sides proportionally.
Q. What is the ratio of triangles?
This means that the ratio of the lengths of the shortest side to the hypotenuse of any 30-60-90 right triangle is 1:2. Therefore, If a triangle is a 30-60-90 right triangle, the ratio of the sides (short leg:long leg:hypotenuse) is 1:√3:2.
Q. What are the side lengths of a 15 75 90 Triangle?
All that remains to know the length ratios for the sides of the 15-75-90 triangle is to determine the length of EC, its hypotenuse, via the Pythagorean Theorem. The square of length EC must equal the square of 1 plus the square of (2 – √3), so EC, squared, equals 1 + 4 – 4√3 + 3, or 8 – 4√3.
Q. How do you find the missing side of a triangle calculator?
How to find the sides of a right triangle
- if leg a is the missing side, then transform the equation to the form when a is on one side, and take a square root: a = √(c² – b²)
- if leg b is unknown, then. b = √(c² – a²)
- for hypotenuse c missing, the formula is. c = √(a² + b²)
Q. What is the missing side of a triangle?
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.
Q. What is the rule for sides of a triangle?
The sides of a triangle rule asserts that the sum of the lengths of any two sides of a triangle has to be greater than the length of the third side. See the side lengths of the acute triangle below. The sum of the lengths of the two shortest sides, 6 and 7, is 13.
Q. What is the sum of all 3 sides of a triangle?
Thus, we can say that a triangle is a polygon, which has three sides, three angles, three vertices and the sum of all three angles of any triangle equals 180°.
