Answer:
<em>Answer: SAS</em>
Step-by-step explanation:
We must prove that triangles ABC and EDC are congruent.
Since BD bisects AE, then AC is congruent with CE.
Since AE bisects BD, then BC is congruent with CD
Angle C is 90° in the triangle EDC and is also 90° in triangle BCA because they are vertical angles.
Being two sides and the included angle congruent, then both triangles are similar by the SAS theorem.
Answer: SAS
Answer:
1000
Step-by-step explanation:
Let the total number of children in school be y.
Then according to the question (4/5) of children are boys.
Then as we know that the sum of fractions is 1.
The fraction of girls in school is
1 - (4/5)= (1/5)
So this means (1/5) of the total children in school are girls which means
Y × (1/5) =200 , according to question.
Which gives y =200×5=100
This means that the total number of children in school is 1000.
