Is it possible for a triangle to have two lines of symmetry?

No, it's not. Reflecting a triangle about *any* line has to move at least one corner (if all three stayed in place, they'd all have to be on a line, which is impossible). If the line is a line of symmetry, the result should be the same triangle, which means that the corner got moved to another corner. Reflections don't change angles, so the angles at two corners are equal. If there are TWO lines of symmetry, there's two DIFFERENT pairs of equality between the angles: angle A equals angle B, and angle B equals angle C. But then, a third pair of equality has to exist: angle A must equal angle C. This means the triangle is equilateral, and has three lines of symmetry! So the only way for the triangle to have two lines of symmetry is for it to have three.


How do yo work out the area for a triangle?

draw a straight line down from the middle of the top point (vertex) of the triangle. Measure the base and height and multiply it. whats half of the number you got? that's your answer. thanks for asking!


How do you find the value of variables for a triangle?

They have to be across from each otherJoin the equationsSolveYou will know if you got it right if your slope is the same for both sides


What is the height of an equilateral triangle with the side lengths of 8 inches?

Equilateral triangle means that all sides are equal in length. When it is asked for a height of equilateral triangle it refers to vertical distance from highest point of the triangle to the lowest(Right in the middle). So we got two known and one unknown which tells us that we can use Pythagorean Theorem C2=A2 + B2 A=4 B=? C=8 Solve for B and you will get answer Square root of 48.


What is the measure of f?

In a triangle, sum of three angles is always 180 deg Thus, here F measures 180-(120+30) = 30 deg. Hope you got it. :)

Has a triangle got 2 lines of symmetry and 2 lines of rotational symmetry?

First of all, your grammar is terrible. The question should be "Does a triangle have 2 lines of symmetry and 2 lines of rotational symmetry? and the answer is no. A triangle can not have 2 lines of rotational symmetry, because you only rotate the image, you do not use any lines.


How many parallel sides has a equilataral triangle got?

A triangle, no matter the type, can never have any parallel sides. To try this out, draw any two parallel lines on a sheet of paper and try to make a triangle out of it.

How do you identify which lines are parallel?

Well the easiest way to do this (but in no way perfectly accurate) would be to extend both lines as far as you can on either end. If the lines never meet on either side you've got parallel lines. Well, either that or you're not drawing straight lines, or you haven't drawn them out far enough. The accurate way would be to draw a perpendicular line from one of them towards the other and measure the angle against the second line. If it's perpendicular to both lines you've got yourself parallel lines.
