What is the measure of the other side of the triangle? (1 point) 7.5 m 8.1 m 9.4 m 9.8 m 5. You want to divide a square piece of paper into two equivalent triangles. If the square measures 20 cm on each side, what will the third side of each triangle measure? (1 point) 8.9 cm 20 cm 28.3 cm 2 years ago 2 years ago

Answer: Find a good textbook. There are previous editions of geometry textbooks online for like 2 dollars.

2. ngocthi0101 Group Title

yea

3. No-data Group Title

Ok, what do you know about right triangles?

4. ngocthi0101 Group Title

a little

5. ErikaaLynn Group Title

nothing much really to be honest , i alway suckedd at math

6. ngocthi0101 Group Title

i have lunch, see u later

7. No-data Group Title

Ok have you been taught a theorem called the pithagorean theorem. or something like that?

9. No-data Group Title

Does it makes sense to you the drawing Suroj just posted?

10. ErikaaLynn Group Title

yea im confusedd !

11. No-data Group Title

Well the lenght sides of a triangle must satisfy the equation \[a^2=b^2+c^2\]

12. ErikaaLynn Group Title

oh okay :)

13. No-data Group Title

Ok, knowing that, can you do the problem #3 by yourself?

14. Shayaan_Mustafa Group Title

@ErikaaLynn are you there still?

15. ErikaaLynn Group Title

yea !

16. Shayaan_Mustafa Group Title

17. ErikaaLynn Group Title

18. Shayaan_Mustafa Group Title

ok. in Q#3 and Q#4 you have given a right-angled triangle. right.

19. ErikaaLynn Group Title

yea

20. Shayaan_Mustafa Group Title

Right angled triangle follows a law, the pythagorean law.\[(hypotenuse)^{2}=(perpendicular)^{2}+(base)^{2}\] \[a ^{2}=b ^{2}+c ^{2}\]

21. ErikaaLynn Group Title

oh okay

22. Shayaan_Mustafa Group Title

so in Q#3 take each and every choice and try to satisfy the above equation.

23. ErikaaLynn Group Title

yea , i think . to be honest im not good at mathh !

24. Shayaan_Mustafa Group Title

\[a) 29^{2}=22^{2}+20^{2}\]841=844 (Don't satisfy) b)\[15^{2}=12^{2}+10^{2}\]225=244 (Don't satisfy) c)\[28^{2}=24^{2}+7^{?}\]784=625 (Don't satisfy)

25. Shayaan_Mustafa Group Title

try last option by yourself. remember the longest side will always be the hypotenuse.
