What is the point called where two lines intersect?

Intersecting lines The point where the lines intersect is called the point of intersection. If the angles produced are all right angles, the lines are called perpendicular lines. If two lines never intersect, they are called parallel lines.

What is the center point of an equilateral triangle?

The centroid or centre of mass of an equilateral triangle is the point at which its medians meet.

What do the lines on an equilateral triangle mean?

Types of triangle An isosceles triangle has 2 sides of equal length. The dashes on the lines show they are equal in length. The angles at the base of the equal sides are equal. An equilateral triangle has 3 sides of equal length. The dashes on the lines show they are equal in length.

Where do lines intersect?

point of intersection
When two lines share exactly one common point, they are called the intersecting lines. The intersecting lines share a common point. And, this common point that exists on all intersecting lines is called the point of intersection. The two non-parallel straight lines which are co-planar will have an intersection point.

What is a ray line?

A ray is a part of a line that has one endpoint and goes on infinitely in only one direction. You cannot measure the length of a ray.

What are the lines in a triangle called?

The three altitudes of a triangle converge at a point called orthocenter. A median is a line that connects the vertex of a triangle to the midpoint of the opposite side. The three medians of a triangle converge at a point called centroid or geometric barycenter or center of mass.

What does one lines on a triangle mean?

Little tick marks are used to show that two sides are the same length (congruent). You can use just one tick mark, two or three or more — just as long as you use the same number on sides that are equal.

What is the point called where all of the altitudes of a triangle intersect?

The orthocenter
The orthocenter is the point of intersection of the altitudes of the triangle, that is, the perpendicular lines between each vertex and the opposite side. When the orthocenter is combined with the three vertices, any one of the points is the orthocenter of the other three.
