How do you find which triangle if you know the lengths of the sides of a triangle whether it is isosceles or equilateral or scalene?
You look at the lengths of the sided of the triangle. If the two lengths are same, the triangle is an isosceles triangle. If all the lengths are same, the triangle is an equilateral triangle. If none of the lengths are same, the triangle is a scalene triangle.
How do you calculate missing angles when only given one angle and two lengths?
You'd have to know some relationship, formula, equation etc. among the angles and the lengths. There would be many relationships to choose from if the items you mention are the parts of a triangle, but if they are, you've kept it a secret.
What is the perimiter of a triangle?
A triangle (as you may know) by definiition has 3 sides; if you add up the lengths of all 3 sides, that total is called the perimeter.
How do you find the length of the diagonals of an irregular quadrilateral?
You would have to consider a triangle formed by one diagonal and two sides of the quadrilateral. If you know the lengths of these sides, and the measure of the angle between them, you can use the cosine law to find the diagonal. c2 = a2 + b2 -2ab(cosC)
How do you solve the lengths of a triangle using only all the angles?
You can't. You must know at least one length and at least two angles, or vice versa.
How do you find which triangle if you know the lengths of the sides of a triangle whether it is isosceles or equilateral or scalene?
You look at the lengths of the sided of the triangle. If the two lengths are same, the triangle is an isosceles triangle. If all the lengths are same, the triangle is an equilateral triangle. If none of the lengths are same, the triangle is a scalene triangle.
What is history of theodolite?
From geometry, we know that it is possible to calculate unknown lengths and angles of a triangle given particular information regarding the other angles and lengths of the sides of a triangle. For example, given beginning coordinates such as (x,y) in plane coordinates or the latitude and longitude, it is then possible to calculate new coordinates by measuring certain angles and distances (lengths of sides of a triangle).
Are trigonometric functions used to find the acute angles of a right triangle?
they can be, depending on the information that you are given. If you know lengths of sides, then YES.
How do you find the area of a triangle when given 3 angles and the perimeter?
If you know the lengths of 2 sides and the included angle then use: Area of a triangle = 1/2*a*b*sinC
How do you find the side length on a triangle with one angle given?
To find side lengths on a triangle, you need to know at least one of the sides. The possible combinations for solving* a triangle are: side, side, side; side, angle, side; angle, side, angle; angle, side, longer side. *To solve a triangle is to find the lengths of all the sides and the measures of all the angles.
How do you find the legs of a 90 angle triangle?
Use Pythagoras' theorem if you know any two lengths of the triangle
What is the formula for perimeter of a right triangle when one side is missing?
Surely you know how to find the third side of a right triangle, when you know the lengths of the other two. Find it, and then add up the lengths of the three sides to get the perimeter.
How do you calculate hypotenus length of right triangle?
You use the information you're given, combined with all of the equations, formulas,and relationships you know concerning the parts of a right triangle, to find the itemof information that you don't know yet. So the process you follow depends on theinformation you're given.For example, if you're given the lengths of the two legs of the triangle, and you'retold that the triangle is a right triangle, then you use the Pythagorean equationC2 = A2 + B2to find the length of the hypotenuse.
Is it possible to build a triangle with the lengths of 3 cm 4 cm and 5cm?
yes it is. When you're dealing with the Pythagorean theory, a 3,4,5 triangle is a special triangle. For example, if a triangle has side lengths of 3cm and 4cm, then you automatically know that the other side length is 5cm. It also works if the side lengths are 5cm and 4cm or 5cm and 3cm.
Can you use Trigonometry if you only know the sides of the triangle?
Do you mean you know the lengths of the sides but you don't know the size of any of the angles ? If that's the situation, then yes. The lengths of the sides tell you everything about the triangle, and they define one and only one unique triangle. With a little bit of trig, you can figure out what the size of each angle has to be.
How do you find the are of a triangle with a missing base?
That really depends what else you know about the triangle. For example, if you only know the lengths of two sides, you simply don't have enough information.
How do you calculate missing angles when only given one angle and two lengths?
You'd have to know some relationship, formula, equation etc. among the angles and the lengths. There would be many relationships to choose from if the items you mention are the parts of a triangle, but if they are, you've kept it a secret.
