What are rigid rectilinear figures?
The only rectilinear figure is a triangle, or one composed of several triangles joined together.
Can an Isosceles triangle make a reptile?
No, only adult reptiles can make reptiles. If you're familiar with the concept of Tangrams, you can make several reptiles from the seven shapes, after having putting them together to make an isosceles triangle.
How do you find the mean length?
Make several measures of the length and add the results together. Divide by the number of measurements taken.
How many lines of symmetry does a polygon have?
This varies according to the polygon. A polygon is any 2D closed shape with three or more straight sides. Therefore, a polygon such as a square will have four lines of symmetry, but an irregular hexagon may have several or none. Even a triangle can have between zero and three lines of symmetry, depending on the type of triangle it is.
An isosceles triangle has a measure of 70o what is the measure of each base angle?
To figure out what the measure of the base angles in an isosceles triangle are, it is important to first understand several things about an isosceles triangle. 1. A triangle has 180 degrees. 2. An isosceles has two equal sides, which means that it also has two equivalent angles. 3. In knowing at least any one angle of an isosceles triangle, it is possible to figure out the other two. Since the base angles are unknown in this question, and they are equivalent to one another, it is a simple algebraic problem. 180 - 70 = 2A 180 is the number of degrees in a triangle 70 is the number of degrees taken up by angle C, with angles A and B being the equivalent base angles. 2a is the double of one base angle. Let's solve. 180 - 70 = 2A 110 = 2A 110/2 = A 55 = A The measure of each base angle is 55.
What happened at the triangle shirtwaist factory and what were the results of that disaster?
Several dozen employees of Triangle Shirtwaist, all women and mostly young, died in a fire there, partly because the doors were locked (to prevent employees from leaving early). The result was legislation requiring various safety measures in factories.
Is Easter Island in the Bermuda triangle?
The Bermuda Triangle is not a set defined area, and different accounts of the Bermuda Triangle give different measurements of it. In most of these, there are several islands.
What is the formula for finding an angle in an acute triangle?
There are several different formulas. The best one to use depends on what information you have about the rest of the triangle.
Who invent formula to find the area of triangle?
There are several different formulae for the area of a triangle - depending on the available information - and these were invented by different people.
What states that if the sides of one triangle are congruent to the sides of a second triangle then the triangles are congruent?
It is a congruence theorem. There are several of them and they are not all numbered the same way.
How do you calculate area of a triangle without knowing the height?
There are different formulae, depending on what you DO know. Here you will find several: http://en.wikipedia.org/wiki/Triangle#Computing_the_area_of_a_triangle
How do you prove triangle congruence?
There are several different ways and the answers depend on what is known about the triangles.
How many square miles does Baldwin measure?
Baldwin measures several hundred miles.
What is the answer to the Bermuda Triangle mystery?
Nobody currently knows, but there are several theories you can research. Larry Kusche's book, "The Bermuda Triangle Mystery-Solved" is your best source of info on this.
What is formula of quadrantal spherical triangle?
There is no single formula: there are several, depending on what information you have and what you wish to know.
How do you spell Triancula?
The likely words are:triangular - in a triangle shapetarantula - any of several large spider species
Give a brief history about the pascal triangle?
although the pascal triangle is named after blaise pascal, several other mathematicians applied their knowledge 100 years back before the birth of pascal in1625. jia xian presented this mathematical triangle in 11th century. Yang Hui studied the triangle in 13th century. therefore, it is known as the yang hui's triangle in china.
