What else can I help you with?
Are the lines that contain the altitudes of a triangle concurrent?
Yes. They meet at the orthocentre.
Is a triangle a parallel?
There are no parallel lines in a triangle.
Is a triangle a parallel or a perpendicular?
Perpendicular. Bt ONLY right triangles contain perpendicular lines.
How many pairs of parallel line does a triangle have?
There cannot be parallel lines in any [plane] triangles.
Two sides of a triangle are parallel?
No, Because the lines in a triangle meet, so they cant be parallel because parallel lines never meet.
Are the lines that contain the altitudes of a triangle concurrent?
Yes. They meet at the orthocentre.
Does a acute triangle have parallel lines?
There are no parallel lines in a triangle.
Is a triangle a parallel?
There are no parallel lines in a triangle.
How many pares of parallel lines does a triangle have?
There are 0 parallel lines that a triangle has.
Is a triangle a parallel or a perpendicular?
Perpendicular. Bt ONLY right triangles contain perpendicular lines.
How many sets of parallel lines does a triangle?
how many sets of parallel lines are in a triangle
How many parallel lines does a trangle have?
A triangle can have no parallel lines.
How pairs of parallel lines does a traingle have?
A triangle has no parallel lines
Does a scalene triangle have parallel lines?
no,no triangle does
Does a right angled triangle have parallel lines?
No. Parallel lines are lines that extend in the same direction. In a triangle the lines go in different directions.
How many pairs of parallel line does a triangle have?
There cannot be parallel lines in any [plane] triangles.
Lines that contain the altitudes of a triangle?
The altitudes of a triangle are the segments drawn from each vertex perpendicular to the opposite side. These lines intersect at a point called the orthocenter, which can lie inside the triangle for acute triangles, on the vertex for right triangles, and outside for obtuse triangles. Each altitude represents the height of the triangle from that vertex, contributing to the calculation of the triangle's area. The altitudes can be constructed using geometric methods or calculated using coordinate geometry.
