Triangle has three sides and three angles. The sum length of any two sides is longer than the length of the other side. All angles of a triangle always add up to 180 ̊C. Triangle has three types based on its three angles, including ...

In the given obtuse triangle ΔABC, we know that a triangle has three altitudes from the three vertices to the opposite sides. The altitude or the height from the acute angles of an obtuse triangle lies outside the triangle. We extend the base as shown and determine the height of the obt...
A scalene triangle consists of 3 points or corners. It has 3 unequal length sides. It also has 3 unequal angles. What is an Obtuse, Acute or Right Scalene Triangle? An obtuse scalene triangle has one angle that is over 90 degrees. An acute scalene triangle has all three angles less than...
Set up the equation: (x+3)+(2x-3)+(3x-5)=25 Collect like terms: 6x- 5 = 25 Add 5 to each side: 6x = 30 Divide each side by 6: x = 5 Plugging in 5 for x, we get that the lengths of the sides are 8, 7, and 10. The length of the shortest side is 7. 反馈 收藏...
If two sides of a triangle are congruent, then the angles opposite to those two sides must also be congruent. This is because all three angles in a triangle add up to 180�. Therefore, if two angles in a triangle are the same, then the third angle must be the same as well. The ...
These ratios still apply to the sides of a right triangle when no unit circle is involved and when the triangle is not in standard position and is not being graphed using (x,y)(x,y) coordinates. To be able to use these ratios freely, we will give the sides more general names: ...
