The angle bisectors of a triangle are the lines which cut the inner angles of a triangle into equal halves. The angle bisectors are concurrent and intersect at the center of the incircle.
It's a quadrilateral (4 sides) and it has two sides that are parallel. If you draw a triangle and cut off one corner, you'll have two figures. One is a triangle, and the other, the 4-sided one, will be a trapezium.
YES. 18 and 24 are the two leg lengths and 30 is the hypotenuse then by Pythagoras' Theorem :- 182 + 242 = 302 324 + 576 = 900......which is true and therefore the three side lengths 18, 24 and 30 do form the sides of a right-angled triangle.
trisect
three
Both have equal sides and equal base angles An isosceles trapezoid is made from an isosceles triangle that's had its top cut off parallel to its base
Base angles are equal and sides are equal in length. It looks like a isosceles triangle that has had its vertex cut off parallel to its base.
By angle: a right triangle. By sides: an isosceles triangle.
Break it down. Hexa means six so it has six sides. And tri means three so it has three sides. Draw it and you will see. Heres a hint. You'll have two when you finish
9
9, 4, and 11 are three dimensionless numbers. Yes, they can represent the lengths of the sides of a triangle. You can take three straight sticks, cut them to lengths of 9, 4, and 11 inches, then lay them down on a table so that the ends hook up and they form a triangle.
cut it like a triforce
because it has equal sides and you can fold it anyway and it will still have equal sides
The difference between plane and spherical triangles is that plane triangles are constructed on a plane, and spherical triangles are constructed on the surface of a sphere. Let's take one example and run with it. Picture an equilateral triangle drawn on a plane. It has sides of equal length (naturally), and its interior angles are each 60 degrees (of course), and they sum to 180 degrees (like any and every other triangle). Now, let's take a sphere and construct that equilateral triangle on its surface. Picture an "equator" on a sphere, and cut that ball in half through the middle. Set the top half on a flat surface and cut it into four equal pieces. Now if you "peel up" the surface of one of those quarters and inspect that triangle, it will have three sides of equal length, and will have three right angles. Not possible on a plane, but easy as pie on the surface of a sphere. Spherical trig is the "next step up" from plane trig.
