Calculate the length of the oblique side of a right triangle
It is known that the hypotenuse of a right triangle is 69 degrees from the bottom and 21 degrees from the top


Hypotenuse = 10 △ sin69 ° = 10 / 0.934 = 10.71

Why is there only verb prototype, verb past tense, past participle but no present participle in the word list?


Verb prototype is to prompt what word, and the past tense and past participle of verb have many irregular changes, such as sing's past tense is sang, past participle is sung; come's past tense is cam, past tense is come, learn's past tense and past participle are the same, each has two kinds: learn and learned

In the triangle ABC, ad is the middle line on BC, f is the point on AC, BF intersects ad at e, and AF: FC = 3:5, then AE: ED is obtained


Make BF parallel line from D intersect AC with G
Because: dg / / BF, BD = CD
So: CG = FG
And because: AF: FC = 3:5
So AF: FG = 3:2.5 = 6:5
So AE: eg = AF: FC = 6:5

Taking the sides AB and AC of △ ABC as the hypotenuse, make right triangle abd and ace to the outside of △ ABC, ∠ ADB = ∠ AEC = 90 ° and ∠ abd = ∠ ace, M is the midpoint of BC
Verification: DM = em


Take the midpoint F of AB and the midpoint g of AC, and prove △ DMF ≌ MEG by SAS, then DM = em
1) F is the midpoint of the hypotenuse of the right angle △ abd = > DF = (1 / 2) ab
M is the midpoint of BC, G is the midpoint of AC = > mg = (1 / 2) ab
So DF = mg
2) Same as 1) FM = eg
3) FM//AC => ∠BFM=∠BAC
GM//AB => ∠CGM=∠BAC
Therefore, BFM = CGM
And ∠ abd = ∠ ace = > BFD = 180 ° - 2 ∠ abd = 180 ° - 2 ∠ ace = ∠ CGE
Thus, DFM = MGE
