No, it does not. As far as I'm only in 5th grade advanced class
No. A pentagon has 5 sides and a triangle has 3 sides.
Because the sum of the smaller sides is greater than the largest side and it is possible to construct one right angle triangle with the given lengths
A scalene triangle has three sides of different lengths. A right triangle can be scalene - for instance the '3-4-5' triangle has a right angle opposite the side which is 5 units long.
Triangular numbers enumerate the items that can be arranged in a triangle. For example, ten blowling pins (10 is 4 triangled) and fifteen bowling pins (15 is 5 triangled). Applications might include counting band members in a triangle formation, or napkins in a triangle pattern at a wedding. - Bill
3, 5, 5 does not make a right angle triangle but they can make an isosceles triangle Correct. Try 3,4,5. That will be a right triangle. 3x3 plus 4x4 = 5x5

No it does not.
No
Yes if the match sticks are the same length it's possible to make an isosceles triangle with them
3 4 5
Yes
Try it out... Draw a triangle with 5 cm sides and see if you can make them fit.
No
5
Yes because 3, 4 and 5 complies with Pythagoras' theorem for a right angle triangle.
