What of a triangle is a segment drawn through the midpoint of a side forming a right angle?
It is the perpendicular bisector
Can a triangle have two perpendicular sides?
Yes. If it is a right triangle, the angle opposite the hypotenuse will be right, 90o, therefore if the lines forming the angle were to continue, they would be perpendicular. What's the question?
How many acute angle in the letter A is?
Three, forming the triangle above the line. The two angles below the line are obtuse.
Is there a symbol for due to?
Yes, it is an upside down "therefore" symbol. i.e. three dots forming a triangle with a flat top and point at the bottom.
It is impossible for a triangle to be both isosceles and right?
No. Think of a triangle with two 45o angles. These must be opposite equal sides which in turn form a right angle. Imagine a square divided into 4 by diagonals, forming 4 isosceles right-angled triangles.
Why do engineers use triangles in construction?
► Because it remains rigid. there is only one way to connect 3 lines into a triangle (think about beams and connectors). the structural strength comes from the beams and the connectors. the strength of the connectors is needed to keep the beams together, but the real strength comes from the beams. as long as they don't stretch/shrink, the triangle will be stable. for a rectangle, the same beams/connectors could be used for a parallelogram. all of the structural strength would have to be in the connectors. if the beams are allowed to pivot at the corners, you will loose the structure
How does the human brain learn?
By forming an neural network
Which type of network connects each node to the next forming a loop Which type of network connects each node to the next forming a loop?

What does it mean when you have three freckles forming a triangle on your chest?
You're dying..
Can PC'a and Mac's be linked to the same business network?
It is possible and easy to connect them all to the same network. Just choose the network that you are interested in forming at network settings.
What is a pentagonal pyramid?
a pentagonal pyramid is a shape with a base of a triangle, and triangles forming up to the point
What Does the triple dot thing mean?
Three dots forming a small triangle means "therefore"
What of a triangle is a segment drawn through the midpoint of a side forming a right angle?
It is the perpendicular bisector
What makes the Eiffel Tower rigid?
In geometry, the triangle form is the most rigid. The length of the sides define the shape of the triangle and anything made of triangles will maintain that rigidity. Looking at the Eiffel Tower you will notice that the whole structure is composed of metal beams meeting to form triangles. The metal beams themselves are made of smaller triangle structures.
What is a disadvantage of a truss bridge?
It is very hard because it is the strongest.
Does a triangle have a curved side?
No. A triangle is a closed shape made of three straight lines, joined at their endpoints forming three vertices and three angles (hence tri-angle).
Can a triangle have two perpendicular sides?
Yes. If it is a right triangle, the angle opposite the hypotenuse will be right, 90o, therefore if the lines forming the angle were to continue, they would be perpendicular. What's the question?
