How can you use a reflection to find a missing vertex in a square?
Given three vertices, the two that are the furthest apart lie at the ends of a diagonal. Reflect the square in this diagonal. The third vertex will be where the missing vertex should be.
What are the three names of a regular triangle?
Regular, Acute, and Equilateral * * * * * Regular and Equilateral are correct but not Acute. An acute triangle with angles of 50,60 70 degrees for example, is not regular. An equiangular triangle is the third possible name.
What is a reuleaux triangle that has a diameter of 1.5mm?
It is a plane shape of constant width = 1.5 mm. You can construct it in two ways:Draw an equilateral triangle with sides of 1.5 mm. From each vertex, draw an arc between the other two vertices; orDraw a circle of radius 1.5 mm. From any point on its circumference draw another circle with the same radius. From one of the points of intersection of the two circles, draw a third. The intersection of the three circles is the required shape.
An isosceles triangle is equilateral?
No, isosceles and equilateral are two separate types of triangles. Isosceles triangles have only two congruent sides, while all three sides of an equilateral triangle are congruent.
What are the reasons used in the proof that the equilateral triangle construction actually constructs an equilateral triangle?
The answer to this question is Two segments that are both congruent to a third segment must be congruent to each other All of the radii of a circle are congruent You're welcome.
What is the length of the third side of an equilateral triangle have?
The length of the third side of an equilateral triangle is the same as the lengths of both of the other two sides.
Why does Wiki say that equilateral triangles are isosceles?
An equilateral triangle is a special type of isosceles triangle. It has two equal sides, which makes it isosceles; its third side is also equal, making it equilateral, too.
If two angles in a triangle are congruent to two angles in another triangle what can you conclude about the third angle on both triangles?

How is an equilateral triangle an isosceles triangle?
An equilateral triangle, by definition, has three sides of equal length. The definition for an isosceles triangle is that it must have two sides of equal length, the other side being free to have any length. Based on these two definitions, we can say that an equilateral triangle is a special case of the isosceles triangle, namely one where the third side is also equal to the other two sides.

How many axes of symmetry has a equilateral triangle?
For an equilateral triangle, there are three axes of symmetry. A plane figure is symmetrical about the line l if, whenever P is a point of the figure, so too is P', where P' is the mirror-image of P in the line l. The line is called a line of symmetry (or axis of symmetry), and the figure is said to be a symmetrical by the reflection in the line l. An equilateral triangle with reflection symmetry has two halves that are mirror images of each other. If the shape is folded over its line of symmetry, the two halves of the shape match exactly. So, we can say that the two halves of an equilateral triangle are matched exactly only when its shape is folded over the lines of symmetry that passes through their vertixes and the midpoint of its sides. Thus, an equilateral triangle has three lines of symmetry, and three angles of rotation. If you rotate any shape a full turn, it will look like it did before you rotated it. When you rotate a shape less than a full turn about its center point and it looks exactly as it did before you rotated it, it has rotation symmetry. In an equilateral triangle there are three places in the rotation where the triangle will look exactly the same as its starting position. If we turn the triangle one third of a full turn (60 degrees), the vertex 1 will be at position 3, vertex 2 will be at position 1, and vertex 3 will be at position 2, and the triangle will look like its starting position.
What are the measures of all angles in a triangle if 2 sides equal the third side?
If two sides of a triangle are equal in length to the third side, then the triangle is equilateral, and all angles are 60 degrees.
