[ornate coral]

is this correct? also can someone let me know which one is the perpendicular/angle bisector and how i know if they are congruent?

[wind roost]

Perpendicular bisector of a line is the line which divides another line into two equal parts by forming a right angles at the intersection point

Congruent angle here refers to equal angles

Angle bisector is the line which divides an angle into two equal parts

[wind roost]

<EBC is not an obtuse angle

Obtuse angle is the angle which is greater than 90 but smaller than 180

<EBC is greater than 180

<EBC is reflex angle,
Reflex angle is the angle which is greater than 180 but smaller than 360

Also <EBA and <CBF r equal because they r veryically opposite angles

3 f ,BD is the perpendicular bisector cuz it bisects AC at B forming a right angle

[wind roost]

The rest r alright

[ornate coral]

It looks obtuse. How can I tell?

[wind roost]

Oh wait EBC ,other way around is obtuse

[ornate coral]

Huh

[wind roost]

This is obtuse

But this is reflex

[ornate coral]

Ohhh

Thank you

So which ones are wrong and how should I cram?

[wind roost]

3f is wrong

AC is not a perpendicular bisector

[wind roost]

Read this

[ornate coral]

how?

how do i know if its a bsector or not

so LM bisector is correct?

[wind roost]

Read this @ornate coral

Read the previous texts

[wind roost]

This is correct

[ornate coral]

i didd

can u give me some practice questions

[ornate coral]

?

[ornate coral]

how is EBC not obtuse

[wind roost]

U can search up online

[wind roost]

It is obtuse

[ornate coral]

u said it was reflex

[ornate coral]

i couldnt find any

even khan academy

[wind roost]

Yea in one way it is,in other way it is obtuse

I explained late4

[ornate coral]

ok

[wind roost]

I dont hv sources

[ornate coral]

for perpendicular bisector part

[wind roost]

Regarding this

[ornate coral]

how is LM bisector

couldnt they both be bisectors?

[wind roost]

The parks on PQ line represents that the line LM divided PQ into two equal parts

Bisectors r those which divide PQ in two equal parts

Here LM is perpendicular on PQ plus it divides PQ into two equal parts that's y LM is bisector

They didnt say that PQ bisects LM as well

[ornate coral]

what parks

[wind roost]

That's we xant call PQ perpendicular bisector

[ornate coral]

the ticks?

[wind roost]

Marks*

[ornate coral]

so ticks

[ornate coral]

yea

the lines

short

[wind roost]

That represents that the parts r equal

[ornate coral]

the line or box?

pray for me ok

[wind roost]

The line

[ornate coral]

thats the only thing i struggle with

adding is easy

so the opposite line that doesnt have the ticks is the bisector always?

[wind roost]

U need to notice uf there r ticks

Ticks would mean that the sides r equal

And if the sides r equal that would m3an the other line which cut the line into two equal part is rhe bisector

[ornate coral]

so im right?

[ornate coral]

?

[wind roost]

Yes but if u always think of it in that way ,u might mess up

Better to understand y it works

[wind roost]

LM is the perpendicular bisector cuz it bisects PQ by forming a right angle

[ornate coral]

i got a 61/60
