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.
